List each number's factors one by one:

#39#: #1,3, 13,39#

#6#: #1,2,3,6#

Three is the only factor that unites the two numbers.

To find the greatest common factor (GCF) of two numbers, you can use prime factorization or division method.

Using the division method:

Divide the larger number by the smaller number.
Use the remainder as the new divisor and the previous divisor as the dividend.
Continue this process until you obtain a remainder of 0.
The divisor at this point is the greatest common factor.

Given numbers: 39 and 6

Dividing 39 by 6: 39 ÷ 6 = 6 with a remainder of 3

Now, divide 6 by 3: 6 ÷ 3 = 2 with no remainder

So, the greatest common factor (GCF) of 39 and 6 is 3.

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.
