How do you find the gcf using continuous method?

Answer 1

Continuous division, like factor trees and rainbows is a way to notate the process of finding a prime factorization. Example: 30 and 42
30/2 = 15/3 = 5/5 = 1
42/2 = 21/3 = 7/7 = 1

2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF

Answer 2

8/2 = 4/2 = 2/2 = 1

12/2 = 6/2 = 3/3 = 1

24/2 = 12/2 = 6/2 = 3/3 = 1

2 x 2 x 2 = 8

2 x 2 x 3 = 12

2 x 2 x 2 x 3 = 24

Select the common factors.

2 x 2 = 4, the GCF
