5 X 5 X 2 = 50 is the only way by multiplying.
By adding there are quite a few ways. Did you mean by multiplying or adding?
Assume that the answer is a positive integer. Convert 50 into its factor pairs. 1 x 50 2 x 25 5 x 10 As all of the above numbers divide 50 then there are 6 ways. 50 ÷ 1 = 50 : 50 ÷ 2 = 25 : 50 ÷ 5 = 10 : 50 ÷ 10 = 5 : 50 ÷ 25 = 2 : 50 ÷ 50 = 1
(250, 1) (125, 2) (50, 5) (25, 10)
You can divide evenly it by 1, 2, 5, 10, 25, 50, 125 and 250.
The prime factors of 50 are 2 * 5 * 5
2 x 5 x 5 = 50
If you include 1, you'll have an infinite number of answers. If you don't, you have 2 x 5 x 5
2 x 5 x 5 = 50 2 x 2 x 5 x 5 = 100
2 x 5 x 5 = 50
1 x 50 2 x 25 5 x 10
1, 2, 5, 10, 25, 50
The prime factors of 50 are: 2 and 5
1, 2, 5, 10, 25, 50.
