## LCM steps with Example

1. First you will write down your two numbers on a sheet of paper.
Example:
2

4
2. Then you will write about five or so of the numbers that go into your two numbers. (do this to each number for LCM)
Example:
2: 0,1, 2
4: 0, 1, 2, 4

3. If you don't find a lowest number  in the five Keep going until you find the lowest number they both go into.  (sometimes the lowest number can be one of the two numbers itself )

Example
2:0, 1, 2

4:0, 1, 2, 4
5. The answer to this problem is 2 because it is the smallest number that goes into both 2 & 4.

GCF steps with Example

1. First you will write down your two numbers on a sheet of paper.
Example:   3   4
2.Then writ down about five or so of the multiples that go into your two numbers. ( do this to each number for GCF)
Example:

3: 6, 9, 12, 15, 18   4: 8, 12, 16, 20, 243. If you don't find a highest number  in the five Keep going until you find the highest number they both go into.  (sometimes the highest number can be one of the two numbers itself )
