The factor pairs of 14 are 1*14, and 2*7
14 = 1*14, 2*7 14 = 1 x 14 ( 1st factor pairs) = 2 x 7 (2nd factor pairs
Five of them.
5 of them.
4 pairs with 12 to make 48
The factor pairs of 28 are 1*28, 2*14, and 4*7
14 is not a factor of 48 because 48 is not divisible by 14(48 = 14x3 + 6).
(1, 14) (2, 7)
They are: 1, 2, 7 and 14
1 and 14, 2 and 7
GCF(48, 14) = 2.
The GCF is 2.
