It is: 15

The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 45 are: 1, 3, 5, 9, 15, 45 The common factors are: 1, 3, 5, 15 The Greatest Common Factor: GCF = 15

The factors of 15 are: 1, 3, 5, 15The factors of 45 are: 1, 3, 5, 9, 15, 45The common factors are: 1, 3, 5, 15The Greatest Common Factor (GCF) is: 15

The greatest common denominator, like the greatest common multiple, is infinite.

There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

The Greatest Common Factor (GCF) is: 15The GCF is 15.

The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 45 are: 1, 3, 5, 9, 15, 45 The common factors are: 1, 3, 5, 15 The Greatest Common Factor: GCF = 15

The GCF is 15.

The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The common factors are 1, 3, 5, and 15. Therefore, the greatest common factor is 15. You can also determine the greatest common factor from the prime factors. The prime factors of 45 are 3, 3, and 5. The prime factors of 60 are 2, 2, 3, and 5. The common prime factors are 3 and 5, so the greatest common factor is 3 x 5 = 15.

The factors of 15 are: 1, 3, 5, 15The factors of 45 are: 1, 3, 5, 9, 15, 45The common factors are: 1, 3, 5, 15The Greatest Common Factor (GCF) is: 15

The factors of 45 are 1, 3, 5, 9, 15, 45. For them to be common, they need to be compared to another set of factors.

GCF(30, 45, 75) = 15.

The GCF of 135 and 225 is 45. 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 135 are 1, 3, 5, 9, 15, 27, 45, and 135. The factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225. The common factors are 1, 3, 5, 9, 15, and 45. Therefore, the greatest common factor is 45.
