Math - Divisibility Rules!

Today we learned about the rules of divisibility in math.  Fun stuff, right?  I know...not so much.  However, it is very important to learn the rules for seeing if a number can be divided by 2, 3, 4, 5, 6, 9 or 10.  It will greatly help when we start learning about equivalent fractions, factors, prime factorization, and all that fun stuff.  So, you all need to study your rules!

Remember....

A number is divisible by....

2	If the last digit is even, the number is divisible by 2.
3	If the sum of the digits is divisible by 3, the number is also.
4	If the last two digits form a number divisible by 4, the number is also.
5	If the last digit is a 5 or a 0, the number is divisible by 5.
6	If the number is divisible by both 3 and 2, it is also divisible by 6.
9	If the sum of the digits is divisible by 9, the number is also.
10	If the number ends in 0, it is divisible by 10.
