Glossary 1 Factors: 1 of 2 whole #s that are multiplied to get a product e.g. 13,4 fs of 52 because 13x4=52. Divisors: A # that divides evenly into a given #. e.g. 5, 20/5=4 Product: The answer to a multiplication problem. e.g. 2x3=6 is the product

15
Glossary 2 Multiple: repeated addition of a #. e.g. 3x2=6, 3x3=9 Composite: A # with more than 2 fs: e.g. 4=1,2,4, Even: A # that is evenly divided by 2. e.g. 4/2=2 Prime: A # that has only 2 factors; 1 and itself. e.g. Fs of 2=1,2

16
Glossary 3 Abundant: A # that the sum of it’s proper factors is higher than the # itself. e.g. 12= 1+2+3+4+6=16 Dimension: A way to show Factor Pairs. e.g. The table is a dimension of 4 2x2 Factor Pairs: 2 factors of a # multiplied together to get that #

17
Glossary 4 Prime Factorization: A product made out of prime #s by dividing each composite # in the first # into primes and keep on going until the bottom is completely prime. ( all the #s are a factor of the first #) e.g. see extra # stuffprimesextra # stuff The Factor Game is for 2 players, player 1 circles a # then player 2 gets the sum of all the uncircled factors of the # then switch, player 2 chooses a # and player gets the sum of all the factors added together, the game ends when all #s are circle and winner is the one with the most points
