Greatest Common Factor of 10 and 16
GCF(10, 16) = 2, Greatest common factor of 10 and 16 is 2. 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 10 and 16. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 10 and 16 by prime factorization method
We will first find the prime factorization of 10 and 16.
Prime Factorization of 10 is 1, 2, 5 and Prime Factorization of 16 is 1, 2, 2, 2, 2.
- Factorize\( (10) = \) \(1\times 2\times 5\)
- Factorize\( (16) = \) \(1\times 2\times 2\times 2\times 2\)
Now we need to find any which are common for each number (1, 2) and multiply these numbers together.
\(GCF(10, 16) = 1\times 2 = 2\).
Greatest Common Factor of 10 and 16 by matching factors method
List of positive integers factors of 10 leaving a remainder zero is 1, 2, 5, 10
List of positive integers factors of 16 leaving a remainder zero is 1, 2, 4, 8, 16
As you can see, 2 is the greatest and common number that 10 and 16 divides into.
So the greatest common factor 10 and 16 is 2.
\(GCF(10, 16) = 2\).
