Divisibility Rules

A number is divisible by:

2 – if it is even (the last number has to end in 0, 2, 4, 6, or 8)
      	EX: 512

3 – if the sum of the numbers is divisible by 3
 	EX: 681 -> 6 + 8 + 1 =15 and 3 goes into 15 evenly, so it will go    
into 681 also.

4 – if the number formed by the last 2 numbers is divisible by 4
	EX: 716

5 – if the number ends in 5 or 0
	EX: 315

6 – if it is divisible by BOTH 2 and 3
	EX: 738 (ends in an even number and 7 + 3 + 8 = 18, which is 
divisible by 3)

9 – if the sum of the digits is divisible by 9
	EX: 207 > 2 + 0 + 7 = 9, and 9 goes into 9 evenly

10 – if the number ends in a zero
	EX: 340
