Answer 1

The greatest common factor of 24, 32 = 8
Factors of 24 are 1,2,3,4,6,(8),12,24;Factors of 32 are 1,2,4,(8),16,32

32,48,96 = 16
Factors of 32: 1,2,4,8,(16),32
Factors of 48: 1,2,3,4,6,8,12,(16),24,48
Factors of 96: 1,2,3,4,6,7,12,(16),24,32,48,96

10w = 2 * 5 * w
5w = 5 * 1 w
GCF = 5w

16xy = 2 * 8 * x * y
24xy = 3 * 8 * x * y
GCF = 8xy

21ab = 3 * 7 * a * b
35a = 5 * 7 * a
GCF = 7a

10jk = 2 * 5 * j * k
15k = 3 * 5 * k
GCF = 5k

3mn = 3 * m * n
9mn = 3 * 3 * m * n
12mn = 3 *4 * m * n
GCF= 3mn
