## Using the LCM (Least Common Multiple) to Solve Problems In a previous post, we looked at the Least Common Multiple and how to calculate it. Today we’re going to look at a couple of examples in which we use the Least Common Multiple (LCM) to solve math problems. In one example, we’ll use the LCM to calculate the answer directly, and in the other we’ll […]

## Prime Numbers: Activities with Smartick In previous posts we’ve learned about prime numbers and composite numbers. Today we’re going to look at different sequenced activities involving prime numbers that Smartick students work on. We’ve included examples of different types and levels, from identifying whether a number is prime or composite to finding the least common multiple and highest common factor through prime factor […]
