What are factors and multiples of 12?
if you find the prime factors it makes the number easier to multiple. first make prime factor trees for each of the numbers. i did 18x15. 18 could have 3, 3 and 2 and 15 could have 3 and 5. then the sum could be: 5x2=10x3=30x3=90x3=270 hope this helps. if you are not sure, look up prime factor trees first.
What is the least common multiple of 4 5 15 and 18?
factor the numbers... factors of each: 4 = 2,2 5 = 1,5 15= 3,5 18= 3,6 now multiply each of the factors once per occurrence: 2*1*5*3*6 equals: 180 this is the LCM.
