I'm sure there is a way to turn this, but I've not found it yet. This shows how to find the prime factorization for the number 36. There is more than one way to achieve this, but this is the goal: 2x2x3x3=36.
Tonight's homework has practice for this and practice for using exponents. On the back of the homework page there are a few problems about finding the GCF or LCM. Here is an example using 36 and 42: First, both numbers need deconstructed into their prime factorization (shown above). 36=2x2x3x3; 42=2x3x7
Then find the prime factors they share: 2x3, this will give the GCF for those two numbers (6). Finally, to find the LCM for the two: use the prime factors they share-2x3, then all the other prime factors not already used (2, 3, 7) and multiply them along with the shared primes: 2x3 (the shared primes) x2x3x7=252, which is the LCM.
Hopefully, this (and the sideways picture) will help you and your child understand. Remember, you can contact me via email. [email protected]
