What is the GCF and LCM of 36 and 45?

Answer 1

GCF is #9# and LCM is #180#

This is an intriguing question: the product of any two numbers' GCF and LCM is always equal to the product of the two numbers.

Let's express GCF and LCM as products of prime numbers in order to find them.

#36=2xx2xx3xx3# and
#45=3xx3xx5#
Now we have #3xx3# as the only prime common factors between them and hence, GCF is #3xx3=9#.
As #2# and #3# occur at the maximum two time and remaining factor #5# occurs only once,
LCM is #2xx2xx3xx3xx5=180#
One may check #36xx45=9xx180=1620#

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.
