Best Answer

To find the greatest common factor of a set of numbers, do a prime factorization of each one, then multiply the prime factors that the numbers have in common.

The prime factorization of 54 is: 2 x 3 x 3 x 3

The prime factorization of 81 is: 3 x 3 x 3 x 3

The prime factorization of 135 is: 3 x 3 x 3 x 5

All three numbers have three 3's in common as prime factors, so the GCF of all three numbers is: 3 x 3 x 3 = 27.

The GCF (Greatest Common Factor) of 54 and 135 is: 27

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 54, 90, and 135 is 9

The GCF of 36, 54, and 135 is 9Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.The factors of 135 are 1, 3, 5, 9, 15, 27, 45, and 135.The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9.

The greatest common factor of 54 and 90 is 18.
