Factor:An integer that divides evenly (no remainder) into a numberFactors of 6 are: 1, 2, 3, 6
Multiple:The product of a number and any natural numberSome multiples of 6: 6, 12, 18, 24……
You simply write out all the factors for each number. Then find the greatest number. I like to circle the numbers by using columns.
List the factors of 60:1,2,3,4,5,6,10,12,15,20,30,60List the factors of 961,2,3,4,6,8,12,16,24,32,48,96find the largest factor - 12
Multiples of 12 are…12,24,36,48,60,72,….Multiples of 18 are…18,36,54,72,90,108,…The smallest multiple the 2 numbers have in common is the least common multiple.
