# Lesson goal: Exhaustive divisibility tester

Previous: Divisibility tester (1) | Home | Next: Checking random numbers

In a past lesson, we learned how to use the % or "mod" operator to test if one number is divisible by another number. A simple divisibilty tester was made using this idea.

In this lesson, we'll use a for-loop to (exhausively) check through every number up to a number you wish to test. In this way, we can find all factors of a given number.

# Now you try. Fix the if statement to have a condition that will be true if i divides evenly into num.

This code will not run. What will you fill into the if statement to test if num is divisible by i? Dismiss.
