Question

Answer 1

32550

Answer 2

pls how did u calculate??

Answer 3

Do you know how to get prime factors?

Answer 4

Kawsar i think i can,using the table formula

Answer 5

It's not 32250, that's not a multiple of 62210.
To get LCM, factor each number into its primes:
62210 = 2 * 5 * 62210
75 = 3 * 5 * 5
Then take all unique factors, and for factors that repeat, only consider one of them, (which is why I typed it out this way, so you can see 5 repeats) , i.e
2 * 3 * 5 * 5 * 62210 = 933150
LCM = 933150

Answer 6

Oh, I thought the question was 62, 210 and 75, as in 3 numbers.

Answer 7

Oh I didn't think of that...apologies, it very well could be. Which is it, Cuira?

Answer 8

I just assumed it was 3 numbers as 62210 seemed a very high number. It could be any of the two. lol!
