What is the LCM of 50 75 100?

Answer 1

You can write out the multiples of each of them to see if they match, but that would take a while. Using your brain you could do this much quicker like so:

50 goes into 100, so any multiple of 100 will be a multiple of 50. Since 100 is the greater number, we don't worry about the 50 since we are wanting lowest common multiple.

So now we only have 100 and 75 to worry about. This makes it much easier. Just find a multiple of 75 which ends in 00. 75*4 is 400, which is the lowest common multiple which ends in 00 . 100 goes into it and 50 does as well, so 400 is the LCM.

Hope this helps!
