## What is the GCF for 75 and 30?

The prime numbers 5 and 3 are both factors that are common to 30 and 75.

The product of these factors is 3×5 = 15.

Thus, the “Greatest Common Factor” of 30 and 75 is 15.

To check this result, divide 15 into 30 and then into 75, and verify that in each case the result is a whole number..

## What is the HCF of 30 45?

We found the factors and prime factorization of 30 and 45. The biggest common factor number is the GCF number. So the greatest common factor 30 and 45 is 15.

## What is the HCF of 36 and 48?

12The GCF, or greatest common factor, of 36 and 48 is 12. To find the GCF, you need to first identify the factors of each of the numbers.

## What is the HCF of 42?

HCF Of 42,98,140|GCF Of 42,98,140|

## 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 are the greatest common factors of 30?

The prime factors of 30 are 2 x 3 x 5. The prime factors they have in common are 3 x 5. 3 x 5 = 15. The greatest common factor is 15.

## What is the GCF of 63 and 42?

Greatest common factor (GCF) of 42 and 63 is 21. We will now calculate the prime factors of 42 and 63, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 42 and 63.

## What are all the factors of 30 and 45?

The gcf of 30 and 45 can be obtained like this: The factors of 30 are 30, 15, 10, 6, 5, 3, 2, 1. The factors of 45 are 45, 15, 9, 5, 3, 1. The common factors of 30 and 45 are 15, 5, 3, 1, intersecting the two sets above.

## What are the common factors for 18 and 30?

Greatest common factor (GCF) of 18 and 30 is 6. We will now calculate the prime factors of 18 and 30, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 18 and 30.

## What is the GCF of 30 and 40?

Answer and Explanation: The greatest common factor of 30 and 40 is 10. To find the greatest common factor, start by identifying all the factors for each of the numbers.

## What is the HCF of 36 and 42?

We found the factors and prime factorization of 36 and 42. The biggest common factor number is the GCF number. So the greatest common factor 36 and 42 is 6.

## What is the HCF of 24 and 36?

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18 and 36. Therefore, common factor of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12. Highest common factor (H.C.F) of 24 and 36 = 12.

## What is the LCM of 3 and 9?

Least common multiple (LCM) of 3 and 9 is 9.

## What is the GCF of 30 and 18?

The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder. For example, for the set of numbers 18, 30 and 42 the GCF = 6.

## What is the GCF of 81 and 45?

The common factors of 45 and 81 are 9, 3, 1, intersecting the two sets above. In the intersection factors of 45 ∩ factors of 81 the greatest element is 9. Therefore, the greatest common factor of 45 and 81 is 9.
