**Answer This Question**

I am trying this sec one question

24 = 2x2x2x3

Since 24 is a multiple of n, n MUST contain at the very least, the other 2 factors ie 2x2 since 6 = 2x3.

The answer cannot be 4 becos lcm of 4 and 6 is 12.

The answer is 8 ie 2x2x2.

The LCM of 8 n 6 is 24.

Note that n cannot be 12 ie 2x2x3 becos the lcm of 6 and 12 is 12.
