Greatest Common Factor of 920 and 50
GCF(920, 50) = 10, Greatest common factor of 920 and 50 is 10. 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 920 and 50. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 920 and 50 by prime factorization method
We will first find the prime factorization of 920 and 50.
Prime Factorization of 920 is 1, 2, 2, 2, 5, 23 and Prime Factorization of 50 is 1, 2, 5, 5.
- Factorize\( (920) = \) \(1\times 2\times 2\times 2\times 5\times 23\)
- Factorize\( (50) = \) \(1\times 2\times 5\times 5\)
Now we need to find any which are common for each number (1, 2, 5) and multiply these numbers together.
\(GCF(920, 50) = 1\times 2\times 5 = 10\).
Greatest Common Factor of 920 and 50 by matching factors method
List of positive integers factors of 920 leaving a remainder zero is 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
List of positive integers factors of 50 leaving a remainder zero is 1, 2, 5, 10, 25, 50
As you can see, 10 is the greatest and common number that 920 and 50 divides into.
So the greatest common factor 920 and 50 is 10.
\(GCF(920, 50) = 10\).
