What is the greatest common factor of 36 and 40?

Answer 1

Benjamin Altschul

#4#

One way to calculate the GCF of two numbers is as follows:

Divide the large number by the smaller to give a quotient and remainder.

If the remainder is zero then the GCF is the smaller number.

Otherwise repeat with the smaller number and the remainder.

In our example, proceed as follows:

#40 / 36 = 1# with remainder #4#

#36 / 4 = 9# with remainder #0#

So the GCF is #4#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
