Posted on | by Moogugore

Note: To test divisibility by any number that can be expressed as 2n or 5n, For example, testing divisibility by 24 (24 = 8*3 = 23*3) is . 17, Subtract 5 times the last digit from the rest. Write the original number as 10x+y to separate out the last digit (y) from the number without the last digit (x). Recognize that divisibility by a 17 means you can. times the last digit from remaining truncated number. Repeat the step as necessary. If the result is divisible by 7, the original number is also divisible.

What you can do is iterate over the digits, keeping track of the current value modulo When you get to the end, if the current value modulo (ie 2x17=34, 34 divided by 2 is 17 etc) Did you instead mean to ask if 17 is a prime number/ not divisible by any whole numbers other than.
