Greatest Common Factor of 64 and 39
GCF(64, 39) = 1, Greatest common factor of 64 and 39 is 1. Greatest Common Factor or Greatest Common Divisor of two numbers is the largest integer by which both the numbers can be divided. There are two different methods to calculate Greatest Common Factor of 64 and 39. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 64 and 39 by prime factorization method
We will first find the prime factorization of 64 and 39.
Prime Factorization of 64 is 1, 2, 2, 2, 2, 2, 2 and Prime Factorization of 39 is 1, 3, 13.
- Factorize\( (64) = \) \(1\times 2\times 2\times 2\times 2\times 2\times 2\)
- Factorize\( (39) = \) \(1\times 3\times 13\)
Now we need to find any which are common for each number (1, 1) and multiply these numbers together.
\(GCF(64, 39) = 1\times 1 = 1\).
Greatest Common Factor of 64 and 39 by matching factors method
List of positive integers factors of 64 leaving a remainder zero is 1, 2, 4, 8, 16, 32, 64
List of positive integers factors of 39 leaving a remainder zero is 1, 3, 13, 39
As you can see, 1 is the greatest and common number that 64 and 39 divides into.
So the greatest common factor 64 and 39 is 1.
