Question

Given several denominators, what is their least common multiple?

91113 \boxed{9} \boxed{11} \boxed{13}

Step-by-Step Solution

The least common multiple (LCM) of 9,11, and 139, 11, \text{ and } 13 is the smallest positive integer that is divisible by each of these numbers.

Since there are no common factors other than 1, the LCM is simply the product of these numbers:
