Multiplication (Basic Facts)
Factors are numbers that you multiply together to find the product (answer).
Examples:
Pairs of factors for 12 are: (1, 12), (3, 4), and (2, 6)
If you list the factors, you would write them as follows: 1, 12, 3, 4, 2, and 6
Usually people list them in order from least to greatest, so the factors would be: 1, 2, 3, 4, 6, and 12
