The Divisibility Rules.

Here are the divisibility rules for:
1 - Any whole number (examples: 890, 6531, 33325 etc..).
2 - Any whole number that ends with a 0, 2, 4, 6 and 8 (examples: 50, 9002, 5634, 1188).
3 - The sum of the whole number must have the factor of 3 (example: 1234. 1+2+3+4=10. 10 does not have the factor of 3).
4 - Any whole number that can be divisible by 2 twice (example: 240. 240÷2=120. 120÷2=60. 240 is divisible by 4).
5 - Any whole number that ends with 5 or 0 (examples: 3425, 100 etc..).
6 - The sum of the whole number must have the factor of 6/must be divisible by 2 and 3 (examples: 570. 5+7+0=12. 12 has the factor of 6/12. 12 is divisible by 2 and 3).
8 - Any whole number that can be divisible by 2 thrice (example: 624. 624÷2=312. 312÷2=156. 156÷2=78. 624 is divisible by 8).
9 - The sum of the whole number must have the factor of 9 (example: 6376. 6+3+7+6=22. 22 does not have the factor of 9).
10 - Any whole number ending in 0 (example: 10, 20, 30 etc..).
*These are the rules that we've gone through already*

  3. Very, very detailed! The colors just made everything look like rainbows! Maybe next time add a video or a link to help us learn more. But great job.
