What is the smallest whole number that has a remainder of 1 when divided by 4, a remainder of 1 when divided by 7, and a remainder of 2 when divided by 5?

140n + 57, where n=0, 1, 2, 3......etc.

The smallest whole number = 57

A=4k+1

A=7m+1

A=5t+2

7 is the biggest one so I just looked at the 7 ones and see if they worked for the others.

8,15,22,29,36,43,50,57 Yep, 57 works for the others as well, so that is the smallest one
