Factors, Factor Pairs, Prime, and Composite Numbers

Factors are the numbers you can multiple to get another whole number.

You can list factors two ways: 1. with their pair (the number you multiple it by to get the larger number, or 2. in a list from least to greatest

Prime Numbers only have two factors: 1, and themselves!

No other numbers can be multiplied together to get that prime number

Prime numbers from 0-100 are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97

The are the OPPOSITE of prime

Composite numbers have MORE than two factors!

The easiest way to check if a number is composite is:

to check if it is even, if so 2 will be one of its factors and it would be considered composite

if that isn't the case, see if it ends in 0 or 5, if so 5 would be one of its factors and it would be composite

if it isn't even (ending in 0, 2, 4, 6, or 8) and it doesn't end in 5... then you need to check your multipication chart to see if 3, 4, 6, 7, 8, or 9 is one of that numbers factor's!
