Greatest Common Factor of 52 and 78
GCF(52, 78) = 26, Greatest common factor of 52 and 78 is 26. 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 52 and 78. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 52 and 78 by prime factorization method
We will first find the prime factorization of 52 and 78.
Prime Factorization of 52 is 1, 2, 2, 13 and Prime Factorization of 78 is 1, 2, 3, 13.
- Factorize\( (52) = \) \(1\times 2\times 2\times 13\)
- Factorize\( (78) = \) \(1\times 2\times 3\times 13\)
Now we need to find any which are common for each number (1, 2, 13) and multiply these numbers together.
\(GCF(52, 78) = 1\times 2\times 13 = 26\).
Greatest Common Factor of 52 and 78 by matching factors method
List of positive integers factors of 52 leaving a remainder zero is 1, 2, 4, 13, 26, 52
List of positive integers factors of 78 leaving a remainder zero is 1, 2, 3, 6, 13, 26, 39, 78
