The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into both the composite numbers.
Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF

What is the gcf of 52 and is it prime or composite?
52 is composite. You need at least two numbers to find a GCF.
What is the gcf of any two prime numbers and composite numbers?
One
What are two composite numbers with the GCF of 1?
Any two composite numbers who do not share the same prime factors.15 = 5x322 = 11x2So 15 and 22 have a GCF of 1
What are two composite numbers that have the greatest common factor?
Without specifying the GCF, it could be anything. 9 and 12 have a GCF of 3.
Can you list two composite numbers whose GCF is 4 and whose sum is 28?
No need to answer it anymore.

What are two composite numbers with the GCF of 1?
Any two composite numbers who do not share the same prime factors.15 = 5x322 = 11x2So 15 and 22 have a GCF of 1
Which pair of composite numbers has GCF of 1?
Any two coprime numbers
What are two composite numbers whose GCF is 1?
4 and 9 have a GCF of 1
What are two composite numbers whose GCF is 10?
10,20
Is the gcf of two numbers are always composite number?
Not necessarily.
What is the gcf of all composite numbers under 100?
The GCF of all the composite numbers under 100 is 1. For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.
What are two composite numbers whose gcf is 6?
They could be 12 and 18
Is the greatest common factor of two numbers a composite number?
The numbers are relatively prime, or co-prime.
What are two composite numbers that have the greatest common factor?
Without specifying the GCF, it could be anything. 9 and 12 have a GCF of 3.
Find two composite numbers with a greatest common factor GCF of 1?
25 and 32
