## What are the factors of 18?

Table of Factors and MultiplesFactorsMultiples1, 2, 4, 8, 16161121, 17171191, 2, 3, 6, 9, 18181261, 191913341 more rows.

## What are the highest 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. Another method of finding the greatest common factor is by using prime factorization.

## Is 18 a perfect square?

Is 18 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 18 is about 4.243. Thus, the square root of 18 is not an integer, and therefore 18 is not a square number.

## What are three factors of 18?

Factors of 18: Testing the integer values 1 through 4 for division into 18 with a 0 remainder we get these factor pairs: (1 and 18), (2 and 9), (3 and 6).

## What is the GCF of 24 12 and 18?

1, 2, 3 and 6 are common factors for 18, 24, and 36. The greatest common factor (GCF) is 6.

## What is the GCF of 18 and 27?

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 HCF of 18 and 9?

We found the factors and prime factorization of 9 and 18. The biggest common factor number is the GCF number. So the greatest common factor 9 and 18 is 9.

## What is the GCF of 15 and 9?

We found the factors and prime factorization of 9 and 15. The biggest common factor number is the GCF number. So the greatest common factor 9 and 15 is 3.

## Is 17 a perfect square?

Is 17 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 17 is about 4.123. Thus, the square root of 17 is not an integer, and therefore 17 is not a square number.

## What is the GCF of 18 and 63?

The prime factorization of 63 is: 3 x 3 x 7. The prime factors and multiplicities 18 and 63 have in common are: 3 x 3. 3 x 3 is the gcf of 18 and 63. gcf(18,63) = 9.

## What is the GCF of 2 and 7?
