Question

Greatest common factor of 36 abd 40

Answer 1

`4`

Step-by-step explanation:

Here, we want to get the greatest common factor between the two numbers

This means we want to get the highest number that is a factor of the two

We can start by factoring both numbers as follows;

`\begin{gathered} 36\text{ = 2}*2*3*3 \\ 40\text{ = 2}*2*2*5 \end{gathered}`

Looking at the factors, we can see that 2 * 2 is the highest we can take out as common to both numbers

That means the highest common factor of the two is 4
