operations addend+addend=sum sum-addend=difference factorXfactor=product dividend ÷ divisor = quotient division dividend ---------- = quotient divisor divide by zero any number ÷ 0 = can't do it 0 ÷ any number = 0 0 cannot be a divisor prime number whole number greater than 1 that is divisible only by itself and 1 composite whole number greater than 1 that are not prime prime factors use factor tree - e.g. 36 = 2∗2∗3∗3 GCF greatest common factor the greatest number that will divide evenly into the two numbers list factors of each then chose the highest one LCM least common multiple the smallest product that is a multiple of each of the counting numbers....factor each/ build a product consisting of each factor used the most number of times it appears as a factor. e.g...24=2∗2∗2∗3 36=2∗2∗3∗3 so LCM (24,36) = 2∗2∗2∗3∗3 =72
