1) Think of a two digit number
2) Multiply it successively by 3, 7, 13, and 37
3) What is the result?
For example you r two digit number is 97.
97 x 3 = 291 291 x 7 = 2037 2037 x 13 = 26481 26481 x 37 = 979797
It is the same two digit number repeated three times!
Why does it work?
Since 3 x 7 x 13 x 37 = 10101, then any two digit number ab x 10101 = ababab
ab 59
x 10101 x 10101
