Everyone knows that a number with its units digit equal to 0, 2, 4, 6 or 8 is evenly divisible by two. Here’s a handy way to figure out if a number is divisible by 3. If the sum of the digits of the number in question is evenly divisible by 3 then that number also is divisible by 3.

Example:

Is 64,332 evenly divisible by 3?

Sum the digits of the number: **6 + 4 + 3 + 3 + 2 = 18**

The answer is 18 which is evenly divisible by 3, so 64,332 is evenly divisible by 3.

A nice quick way to find out if 3 is a factor of a number or not!

This example made it so easy to understand for my granddaughter!!

Thanks guys!

Love the website!!

Thanks, Ella! I’m really happy that our site helped. I’ve been writing on math and the brain in our blog, trying to bring the research down from the mountain. I hope you enjoy it, and that your granddaughters keep playing!
