The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
GCF is 18:54 = 18 x 372 = 18 x 490 = 18 x 5
18, 36, 54, 72, 90
Since 18 is a factor of 72, all of its factors are common.
Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. All of the factors of 36 are also factors of 72.
The common factors of 36, 72, and 90 are: 1, 2, 3, 6, 9, and 18
Common factors of 36, 72, and 90 are: 1, 2, 3, 6, 9, and 18.
90-18 = 72
The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The common factors are 1, 2, 3, 6, 9, and 18.
90 - 18 = 72 degrees.90 - 18 = 72 degrees.90 - 18 = 72 degrees.90 - 18 = 72 degrees.

90 - 72 = 18
72 + 18 = 90
The GCF is 18.
The GCF is 18.
The Greatest Common Factor is 18
Change = 90 - 72 = 18 from 72 So % change = 100*18/72 = 100*1/4 = 25%
