## What is the GCF of 18 and 30?

We found the factors and prime factorization of 18 and 30.

The biggest common factor number is the GCF number.

So the greatest common factor 18 and 30 is 6..

## What is the HCF of 16 and 24?

8Example 21 Consider the highest common factor of 16 and 24 again. The common factors are 1, 2, 4 and 8. So, the highest common factor is 8.

## What is the GCF of 12 and 18?

In terms of numbers, the greatest common factor (gcf) is the largest natural number that exactly divides two or more given natural numbers. Example 1: 6 is the greatest common factor of 12 and 18.

## What is the GCF of 15 and 42?

The factors of 42 are 42, 21, 14, 7, 6, 3, 2, 1. The common factors of 15 and 42 are 3, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 42 the greatest element is 3. Therefore, the greatest common factor of 15 and 42 is 3.

## What is the GCF of 4 and 10?

The GCF = 2. Both 4 and 10 are even, so they must have a common factor of 2.

## What is the GCF of 3 and 4?

We found the factors and prime factorization of 3 and 4. The biggest common factor number is the GCF number. So the greatest common factor 3 and 4 is 1.

## What is the GCF of 20 24 and 40?

The common factors for 20,24,40 20 , 24 , 40 are 1,2,4 1 , 2 , 4 . The GCF (HCF) of the numerical factors 1,2,4 1 , 2 , 4 is 4 .

## What is the GCF of 18 and 24?

Consider the numbers 18, 24, and 36. Their common factors are 1, 2, 3, and 6. Their greatest common factor is 6.

## What’s the GCF of 3 and 8?

Greatest common factor (GCF) of 3 and 8 is 1. We will now calculate the prime factors of 3 and 8, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 3 and 8.

## What numbers do 3 and 4 go into?

Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, … Multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, 36, … So, the common multiples of 3 and 4 are 12, 24, 36, …

## What is the GCF of 36 63?

9To sum up, the gcf of 36 and 63 is 9. In common notation: gcf (36,63) = 9.

## What is the GCF of 2 4 and 6?

We here at the Fraction Calculator often determine the Greatest Common Factor (GCF) for numbers such as 2, 4 and 6, because we use the GCF to lower the denominators of our fractions. The Greatest Common Factor of 2, 4 and 6 is the greatest number (factor) that you can evenly divide 2, 4 and 6 by.

## What is the GCF of 7/15 and 21?

The common factors for 7,15,21 7 , 15 , 21 are 1 . The GCF (HCF) of the numerical factors 1 is 1 .

## What is the HCF of 20 and 24?

Greatest common factor (GCF) of 20 and 24 is 4. We will now calculate the prime factors of 20 and 24, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 20 and 24.

## What is the GCF for 4?

Greatest common factor (GCF) of 4 and 8 is 4. We will now calculate the prime factors of 4 and 8, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 4 and 8.
