Math question What is the L.C.M for numbers 72 and 200?

Question

what is the lowest common multipul for 72 and 200

Answer 1

First find the factors of each one.. take ALL of the common factors and then each of the not common factors...

72 = 2*36= 2*2*18=2*2*2*9=2*2*2*3*3
200 = 2*100=2*2*50=2*2*2*25=2*2*2*5*5

common factors = 2*2*2
not common factors = 3*3 and 5*5
take them together.. and get 2*2*2*3*3*5*5=10*10*18= 1800

Answer 2

1800
