The least common multiple of two numbers is their product divided by their greatest common factor. Since 7 is a prime number and 27 is not a multiple of 7, their greatest common factor is 1. The least common multiple is 7 x 27 ÷ 1 = 189.
The Least Common Multiple (LCM) of 9, 7, and 27 is 189.
LCM(27, 7, 9) = 189
Because - if you add all the digits from the number together - they're also exactly divisible by 9. 1+5+7+7+7=27. 27/9=3.
2+7+0=9 and 9 is divisible by 3. Therefore 270 is a multiple of 3.This works for 3,9 and 27.

Because - if you add all the digits from the number together - they're also exactly divisible by 9. 1+5+7+7+7=27. 27/9=3.
21 x 9 = 189 and 27 x 7 = 189. Its right check!
