What is the Least Common Multiple (LCM)?

Back

The LCM of two or more numbers is the smallest multiple that is evenly divisible by all the numbers.

Front

How do you find the LCM using prime factorization?

Back

1. Factor each number into primes. 2. For each distinct prime, take the highest power that appears in any of the factorizations. 3. Multiply these together to get the LCM.

How do you determine the greatest number of fruit cups that can be made from given quantities of fruit?

Back

Find the GCD of the quantities of fruit. For example, GCD(168, 120) = 24, so 24 fruit cups can be made.
