Question

Find the smallest 3-digit number that is exactly divisible
by 6,15,18​

Answer 1

Step-by-step explanation:

First, find the Least Common Multiple of 6, 8 and 12. Simply break down each of those numbers into its prime factors and then multiply those factors as many times as they were needed to generate 6, 8 and 12

Answer 2

LCM of 6, 15 & 18 = 180

The smallest 3-digit number that is divisible by 6, 15 and 18 will also be divided by 180.

[180×1] = 180 (3-digit no.)

Therefore, the smallest 3-digit number that is exactly divisible by 6, 15 and 18 is 180.
