How do you find the GCF of #25k, 35j#?

Answer 1

Riley Anderson

With the GCF (Greatest Common Factor), we're trying to find the biggest value that is a factor for both #25k and 35j#.

#25k=5xx5xxk# #35j=5xx7xxj#

The GCF, or number five, is the only factor that unites the two when compared side by side.

To find the Greatest Common Factor (GCF) of ( 25k ) and ( 35j ), you can use prime factorization method.

Find the prime factors of each term:
- ( 25k ): Prime factorization of 25 is ( 5 \times 5 ), so ( 25k = 5^2 \times k ).
- ( 35j ): Prime factorization of 35 is ( 5 \times 7 ), so ( 35j = 5 \times 7 \times j ).
Identify the common prime factors. In this case, the common prime factor is ( 5 ).
Multiply these common prime factors together. Therefore, the GCF of ( 25k ) and ( 35j ) is ( 5 ).

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.
