I learned that pyramids have a third of the volume of the same based prism with the same dimensions (rectangular based pyramids and rectangular prisms, etc.), as well as cones have a third of the volume of a cylinder with the same dimensions.

I learned the exponent laws, such as adding exponents when multiplying the bases, or subtracting exponents when dividing the bases, and multiplying exponents when it’s a power of a power.

This method is known as “The Ladder Method”

Take two numbers, (i.e. 216 and 144) and put them on an “L” shape

Now, on the left of the “L”, divide the two numbers by the lowest prime factor

Write the quotients below, and do the same for them

Repeat the process until you have two prime numbers left

To find the LCM (432), multiply all of the numbers on the outside and bottom of the ladder

To find the GCF (72), multiply only the left outside of the ladder

I prefer the method of finding the LCM and GCF with prime factorization through the division table.
