Greatest Common Factor of 20 and 301
GCF(20, 301) = 1, Greatest common factor of 20 and 301 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 20 and 301. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 20 and 301 by prime factorization method
We will first find the prime factorization of 20 and 301.
Prime Factorization of 20 is 1, 2, 2, 5 and Prime Factorization of 301 is 1, 7, 43.
- Factorize\( (20) = \) \(1\times 2\times 2\times 5\)
- Factorize\( (301) = \) \(1\times 7\times 43\)
Now we need to find any which are common for each number (1, 1) and multiply these numbers together.
\(GCF(20, 301) = 1\times 1 = 1\).
Greatest Common Factor of 20 and 301 by matching factors method
List of positive integers factors of 20 leaving a remainder zero is 1, 2, 4, 5, 10, 20
List of positive integers factors of 301 leaving a remainder zero is 1, 7, 43, 301
As you can see, 1 is the greatest and common number that 20 and 301 divides into.
So the greatest common factor 20 and 301 is 1.
\(GCF(20, 301) = 1\).
