\[72 = 2 \times 2 \times 2 \times 3 \times3\]\[78 = 2 \times 3 \times 13\]what factors do 72 and 78 have in common?
anonymous
  • anonymous
2 and 3

  • anonymous
so GCF = 2 * 3 ~
anonymous
  • anonymous
Wowwww, so its the numbers 2 and 3, not just one of the numbers?
anonymous
  • anonymous
2 times 3 = 6 = gcf ~ 6 is the gcf
anonymous
  • anonymous
So is 6 the GCF for both numbers
anonymous
  • anonymous
yes

72 can divide by 1, 2, 3, 4, 6, 8, 12, 18, 24, 36, 72 78 can divide by 1, 2, 3, 6, 13, 26, 39, 78. so 6 is the greatest common factors
