Least Common Multiple (LCM)  Factors and Multiples
Least Common Multiple (LCM)
Like GCF, you will also need to do prime factorization to find the Least Common Multiple (LCM) of numbers. After finding out all the prime factors of each number, we then need to multiply each prime factor the greatest number of times it happens in any numbers. In this lesson, we are going to use the "cake method" to solve the questions.
