Greatest Common Factor of 160 and 125
GCF(160, 125) = 5, Greatest common factor of 160 and 125 is 5. 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 160 and 125. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 160 and 125 by prime factorization method
We will first find the prime factorization of 160 and 125.
Prime Factorization of 160 is 1, 2, 2, 2, 2, 2, 5 and Prime Factorization of 125 is 1, 5, 5, 5.
- Factorize\( (160) = \) \(1\times 2\times 2\times 2\times 2\times 2\times 5\)
- Factorize\( (125) = \) \(1\times 5\times 5\times 5\)
Now we need to find any which are common for each number (1, 5) and multiply these numbers together.
\(GCF(160, 125) = 1\times 5 = 5\).
Greatest Common Factor of 160 and 125 by matching factors method
List of positive integers factors of 160 leaving a remainder zero is 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
List of positive integers factors of 125 leaving a remainder zero is 1, 5, 25, 125
