How to find the GCF of 41 and 16 using Prime Factorization
One way to find the GCF of 41 and 16 is to compare the prime factorization of each number. To find the prime factorization, you can follow the instructions for each number here:
What are the Factors of 41?
What are the Factors of 16?
Here is the prime factorization of 41:
4
1
1
41^1
4 1 1
And this is the prime factorization of 16:
2
4
2^4
2 4
When you compare the prime factorization of these two numbers, you can see that there are no matching prime factors. When this is the case, it means that there are no common factors between these two numbers. As a result, the GCF of 41 and 16 is 1.
Thus, the GCF of 41 and 16 is: 1
How to Find the GCF of 41 and 16 by Listing All Common Factors
The first step to this method of finding the Greatest Common Factor of 41 and 16 is to find and list all the factors of each number. Again, you can see how this is done by looking at the “Factors of” articles that are linked to above.
Let’s take a look at the factors for each of these numbers, 41 and 16:
Factors of 41: 1, 41
Factors of 16: 1, 2, 4, 8, 16
When you compare the two lists of factors, you can see that the only common factor is 1. So, in this case, the GCF of 41 and 16 is 1.
