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.
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
The prime factors of 50 are 2 * 5 * 5
2 x 5 x 5 = 50 2 x 2 x 5 x 5 = 100
1 x 50 2 x 25 5 x 10
2 x 5 x 5 = 50
2 x 25 5 x 10
The prime factors of 50 are: 2 and 5
1, 2, 5, 10, 25, 50
