What is the gcf for 18 and 81?

The factors for 18 are 1, 2, 3, 6, 9, and 18.. The factors for 81 are 1, 3, 9, 27, and 81.. Therefore the GCF (Greatest Common Factor) is 9 since it is the greatest number they both share.

What is the gcf of 18 24 36?

Find the factors of all three numbers and then find the largest number that is in each list: i.e. the factors of 18 are 1, 2, 3, 6, 9, 18. So for example, to find the greatest common factor of 21, 28 and 42, find the factors of each: Factors of 21 are 1,3,7,21 Factors of 28 are 1,2,4,7,14,28 Facto (MORE)

Find the GCF of 18 and 54?

Since 18 x 3=54, 18 is the GCF. This is because 18 is a factor of itself and of 54 and certainly there can be no greater factor. Another way to do this is to write each number as the product of its prime factors. 18= 3 2 x2 54=3 3 x2 Now the common factors are 3 2 and 2 and their product is 18 (MORE)
