Greatest Common Factor of 84 and 83

GCF(84, 83) = 1, Greatest common factor of 84 and 83 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 84 and 83. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.

Greatest Common Factor of 84 and 83 by prime factorization method

We will first find the prime factorization of 84 and 83.
Prime Factorization of 84 is 1, 2, 2, 3, 7 and Prime Factorization of 83 is 1, 83.

  • Factorize\( (84) = \) \(1\times 2\times 2\times 3\times 7\)
  • Factorize\( (83) = \) \(1\times 83\)
Now we need to find any which are common for each number (1, 1) and multiply these numbers together.
\(GCF(84, 83) = 1\times 1 = 1\).

Greatest Common Factor of 84 and 83 by matching factors method

List of positive integers factors of 84 leaving a remainder zero is 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
List of positive integers factors of 83 leaving a remainder zero is 1, 83
As you can see, 1 is the greatest and common number that 84 and 83 divides into.
So the greatest common factor 84 and 83 is 1.
\(GCF(84, 83) = 1\).
