In order to find the greatest common factor, we should factorize both terms and identify which factors are common.
Term | Split up into factors |
---|---|
5x | 5⋅x |
25 | 5⋅5 |
When both terms have been broken up into in factors, you see that both contain a 5, and so you can factor this out of the expression. 5⋅x+5⋅5⇔5(x+5)
Proceed in the same way again and start by splitting the terms into factors.
Term | Split up into factors |
---|---|
4a | 2⋅2⋅a |
4b | 2⋅2⋅b |
Split the terms up into factors.
Term | Split up into factors |
---|---|
81x | 3⋅3⋅3⋅3⋅x |
27y | 3⋅3⋅3⋅y |
