GCF of 28 42 and 56 is 14.
The GCF is 14.
(28 = 2 x 14, 42 = 3 x 14, 56 = 4 x 14)
To find the GCF, factor the numbers and multiply their common prime factors:
28 = 2 x 2 x 7
42 = 2 x 3 x 7
56 = 2 x 2 x 2 x 7
Common factors are 2 x 7 = 14
GCF(14, 28, 42) = 14.
LCM(56, 84) = 168 GCF(56, 84) = 28
The GCF is 28.
28 is a factor of 56, and 28 is also a factor of itself. So the highest common factor of 28 and 56 is 28.
