Question

Find the GFC of each set of numbers
300, 450

Answer 1

GFC: 150

Explanation:

prime factorization of 300: 300 = 2 × 2 × 3 × 5 × 5

prime factorization of 450: 450 = 2 × 3 × 3 × 5 × 5

then multiply all the prime factors common to both numbers: GCF = 2 × 3 × 5 × 5

GCF = 150

Answer 2

The GCF is 150.

The factors of 300 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300

The factors of 450 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

Then the greatest common factor is 150.
