To find the greatest common factor of two numbers, you first need to break them into their prime factors: 15 = 3x5 40 = 2x2x2x5 The next step is to identify any common factors. In this case, the only common factor is 5. Thus, the greatest common divisor of the numbers 15 and 40 is 5.

One way to determine the common factors is to find all the factors of the numbers and compare them. The factors of 15 are 1, 3, 5, and 15. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors are 1 and 5. The greatest common factor is 5.

The factors of 40 are 1,2,4,5,8,10,20 and 40.The factors of 15 are 1,3,5 and 15.So the factors common to both number are 1 and 5

Common factors of 40 and 125 are: 1 and 5.

What are the common factors of 15, 25 and 40

The greatest common factor is two.

There is not a greatest common factor of 40 because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The greatest common factor of 16 and 40 is 8. The greatest common factor of 40 and 55 is 5. The greatest common factor of 36, 40, and 96 is 4.

Factors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30. Factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40. Find the greatest factor they both have in common. That is the greatest common factor.
