 # Question: What Are The Common Factors Of 15 And 18?

## 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 HCF of 18 and 48?

We found the factors and prime factorization of 18 and 48. The biggest common factor number is the GCF number. So the greatest common factor 18 and 48 is 6.

## What is the GCF of 18 and 45?

Answer and Explanation: The ‘GCF’ is the ‘greatest common factor’ that is shared between two numbers. Between 18 and 45, the GCF is 9, and here’s how you know.

## What are the common factors of 15 and 20?

Greatest common factor (GCF) of 15 and 20 is 5.

## What are the common factors of 15 and 25?

1 AnswerThe Greatest Common Factor of 15and25 is 5.The factors of 15 are 3and5. (the number itself and 1 do not count).The factor(s) of 25 is 5 . After all, it is a square number.The only factor that is in common is 5.(again remember that 1 does not count here -although 1 is common, 5 is higher)

## What is the GCF of 18 and 9?

The biggest common factor number is the GCF number. So the greatest common factor 9 and 18 is 9.

## What are the common factors 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 is the common factor of 5 15 and 25?

Now, as we can see other than 1, 5 is the common factor in the three factorization, hence 5 is the common factor. Now, HCF is defined as the highest common factor. and here, 5 is the only common factor. So, HCF of 5, 15, 25 is 5.

## What is the GCF of 14 and 21?

Greatest common factor (GCF) of 14 and 21 is 7. We will now calculate the prime factors of 14 and 21, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 14 and 21.

## What are the factors of 25?

25 is a composite number, and it is 5 squared. 25 = 1 x 25 or 5 x 5. Factors of 25: 1, 5, 25. Prime factorization: 25 = 5 x 5, which can also be written 25 = 5².

## What is the GCF of 15 and 9?

Greatest common factor (GCF) of 9 and 15 is 3.

## What is the HCF of 18?

Find the highest common factor (H.C.F) of 12 and 18. Factors of 18 = 1, 2, 3, 6, 9 and 18. Therefore, common factor of 12 and 18 = 1, 2, 3 and 6. Highest common factor (H.C.F) of 12 and 18 = 6 [since 6 is the highest common factor].

## What are the common factors of 15?

The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15).

## What are the common factors 18?

The factors of 18 are 1, 2, 3, 6, 9, 18. The factors of 27 are 1, 3, 9, 27. The common factors of 18 and 27 are 1, 3 and 9. The greatest common factor of 18 and 27 is 9.

## What is the GCF for 15 and 30?

The common factors of 15 and 30 are 1, 3, 5, and 15. The greatest common factor is 15.

## What is the GCF of 7 and 10?

The prime factors and multiplicities 7 and 10 have in common are: 1. 1 is the gcf of 7 and 10. gcf(7,10) = 1.

## What is the common factor of 4?

Greatest common factor (GCF) of 4 and 12 is 4. We will now calculate the prime factors of 4 and 12, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 4 and 12.

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

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