One way to determine the greatest common factor 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 42 are 1, 2, 3, 6, 7, 14, 21, and 42.
The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.
The common factors are 1 and 3.
Therefore, 3 is the greatest common factor.
The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.
The prime factors of 15 are 3 and 5.
The prime factors of 42 are 2, 3, and 7.
The prime factors of 84 are 2, 2, 3, and 7.
The prime factors in common are a single 3, so the greatest common factor is 3.
15- 1, 3, 5, 15
42- 1, 2, 3, 4, 6, 7, 14, 21, 42
84- 1, 2, 3, 4, 6, 7, 12, 21, 28, 42, 84
The GCF is 3.
The Greatest Common Factor (GCF) of 15, 42, and 84 is 3.
3
The factors of 15 are:
1, 3, 5, 15
The factors of 42 are:
1, 2, 3, 6, 7, 14, 21, 42
The common factors are:
1, 3
The Greatest Common Factor:
GCF = 3
The greatest common factor is 3. 3 x 7 = 21, 3 x 5 = 15 and 3 x 14 = 42.
