The GCF is "7"... for 63 and 56 7 x 8 = 56 7 x 9 = 63
There are 8 pints in a gallon - so 8 x 63 -504 pints
63
56 / 63 = 7 x 8 / 7 x 9 = 8 / 9 , by cancelling out the top and bottom 7's.
(-7) x (9) = -63
When figuring out what number goes both into 56 and 63, you should look at the factor pairs. 56: 1 x 56, 2 x 28, 4 x 14, 7 x 8 63: 1 x 63, 3 x 21, 7 x 9 7 goes into both 56 and 63.
63 x 63 = 3969
21 x 3/8 = 63/8 = 77/8
There are 3 factor pairs of 63: 63 = 1 x 63 63 = 3 x 21 63 = 7 x 9
