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

Question

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

No problem! Finding the least common multiple (LCM) can sometimes be tricky, but breaking it down by checking divisibility is a good approach. Just remember to consider all the numbers involved and keep checking until you find the one that is divisible by all of them. In this case, the LCM of 20, 50, and 3 is indeed 300. Good job catching that mistake! If you have any more questions, feel free to ask.
