## What is the Greatest Common Factor (GCF)?

Factorization refers to unique probabilities after getting its organized features in the form of a common factor. In which all the factors detached from a single numeric value. The journey of factorization further leads the classification for common factors as Greatest Common Factor.

## Greatest Common Factor Definition

**“In mathematics, the greatest common factor (GCF) of two non-zero integers or more, is the largest positive integer that divides the numbers without a remainder”.** It is also known as the greatest common denominator, the highest common factor (HCF) or the greatest common divisor (GCD).

## GCF Formula

We can smoothly calculate the Greatest factor multiple or GCF by two prominent formulations:

### First Play

When we obtain the entire factors of two or more numbers, and few out of all factors are matched ("common"), then the largest of those common factors is the Greatest Common Factor.

### Second Play

If we represent two numbers (16 & 24) as products of their prime factors.

- 16 = 2 x 2 x 2 x 2
- 24 = 2 x 2 x 2 x 3

We repeatedly get the three 2’s like a common value. Then the multiple of these repeated integers provides us the GCF.

- GCF = 2 x 2 x 2 = 8

Since factorization is not efficient, this is sensible for small numbers. This item expression shows that the best common divisor could be distinguished by the following property: it divides equally, and gcd is a divisor.

## How to Find GCF?

It’s a mathematical fun to estimate the GCF for any particular set of data when there’s proper guidance for its solution. Below, the easiest tracks reflect the resolution for simple to complex questions.

### Greatest common factor worksheet in three steps:

- Find the prime factorization.

Factors of 12: 1, 2, 3, 4, 6, 12.

Factors of 16: 1, 2, 4, 8, 16.

- Excluded out the common factors.

Common factors = 1, 2, 4

- Picked the largest value out of the common factor.

“4” is the greatest common factor.

This way briefly highlights the route for expressive and accurate answers with negligible input of headache.

## How do you find the GCF and LCM fast?

To calculate LCM, one must be familiar with its cleared implementation. More often you build on fractions with discrete denominators you requisite to find the common denominator :

In mathematics, and more precisely in arithmetic, the smallest common multiple (can also be called PPMC, or “smallest common multiple”) of two non-zero integers a and b is the smallest strictly positive integer which is a multiple of these two numbers.

## What are the steps to find LCM?

The LCM could be calculated fastly by acting on these three easiest steps:

- Take out GCF for any two values (like 30 & 14), which is 2.
- Divide 2 with either of the values, say 30/2 = 15.
- Multiply 15 with the second remaining value to get direct LCM.

## GCF Finder

By retaining the above-mentioned details in a summarized manner, one could easily find the solution or Greatest Common Factor. Dealing with multi-dimensional or decimal numerics, the GCF has no specific margins but only a method throughout the heterogeneous conditions could solve it.

## Mathematical Relation for LCM and GCF

If we’ve calculated the lcm out of them both, we can easily find GCF by using the following relation:

**“Product of two values = GCF of the numbers x LCM of the numbers.”**

- Case 1- If HCF is known and LCM is unknown:

$$\text{LCM}\;=\;\frac{\text{Product of numbers}}{\text{GCF of numbers}}$$

- Case 2- If HCF is unknown and LCM is known:

$$\text{GCF}\;=\;\frac{\text{Product of numbers}}{\text{LCM of numbers}}$$

## What is the GCF Calculator?

With the revolutionized techniques in every single alignment of the scientific approach, calculators are still playing an important role. Providing adequate results with a smooth procedure behind and also managing the time ratio of manual calculations.

GCF calculator is also a capital illustration in the circle of factorization and its extensions. By using this calculator the whole integers on-screen directly revert to the exact answer. This is also known as GCF Finder in technical terms and oriented to the way of calculations.

## What is the GCF of 12 and 4?

The greatest common factor of 12 and 4 can be calculated by making prime factorization. Picking matched pairs from both values and then marked out the greatest factor from them.

### Practical Derivation

Prime factorization,

- 12 = 1, 2, 3, 4, 6, 12
- 4 = 1, 2, 4

1, 2 and 4 are common factors and 4 is the Highest Common factor or GCF of 12 & 4.

## How to use the GCF Calculator?

GCF calculator is easy to use and you can get it from online spots. The strategy set for its proper propagation provides us both the procedure wise and direct answer. There’s no specific limit of numbers in the GCF calculator.

- Therefore we can find the calculation from short (12, 24, 4, 30 ) to long (12, 4, 24, 20, 125, 90, 100, 44, 16, 246, 130, 124, 780, 250, 200, 220, 654, 102,. . . . . .) numerical statements.
- After getting the final output, click the clear option and again redirect to the plane screen for new factorization.
