these are the prime numbers to 1,000

Remember prime numbers are those numbers whose only factors are 1 and itself. Also, know that 2 is the ONLY positive prime number. This will help you find the prime numbers of any set because you can automatically eliminate even numbers (except 2).

Than it is a matter of thinking each odd number through.

Good luck and have a great day!

must be even to be divisible by 2

must add up to a number divisible by 3 (71 adds up to 8 and is not divisible by 3) (72 adds up to 9 and is divisible by 3.

ends with zero or five to be divisible by 5.

for 7, you just have to try to divide it.
