how would i find least common multiple of 20, 50 and 3 ?

okay well you take the 50 and times it by ever number
50--> is it divisbile by 3 NO so not the least common multiple
50x2=100 --> is it divisible by 3 NO, so not the least common multiple

50x3=150 --> is it divisible by 3 YES, is it divisible by 20 NO, so not the least common multiple

50x4=200--> is it divisible by 3 YES
is it divisible by 20, YES

That means 200 is least common multiple of 3, 20, and 50!
hope that helped!

actully it is 300 because 200 is not divisiable by 3

soory my bad, it is 6 X 50 whcihc equals 300

SO yeah sorry do you get the hang of it?

yea lol thanks
