99 x 10 - 99 x 9 = 99(1 x 10 - 1 x 9) = 99(10 - 9) = 99(1) =99
99 x 9 = 891
There are three:99 = 1 x 9999 = 3 x 3399 = 9 x 11
1 x 99, 3 x 33, 9 x 11, 11 x 9, 33 x 3, 99 x 1
The GCF of 27 and 99 is 9 3 x 9 = 27, 11 x 9 = 99
1 x 99 = 99 3 x 33 = 99 9 x 11 = 99
1 x 99, 3 x 33, 9 x 11, 11 x 9, 33 x 3, 99 x 1
