The only factor they have in common is the number 1.
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, 100
42 out of 50 = 100*42/50 = 42*100/50 = 42*2 = 84%
Factors of 50: 1, 2, 5, 10, 25, and 50.Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.The only numbers that are factors of both 50 and84 are: 1 and 2
What is 42% of 50:= 42% * 50= 0.42 * 50= 21
50 is 42% of= 50 / 42= 50 / 0.42= 119
the factors of 42 are 1,42,6,7,2,21,3,14
