Greatest Common Factor of 88 and 38
GCF(88, 38) = 2, Greatest common factor of 88 and 38 is 2. 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 88 and 38. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 88 and 38 by prime factorization method
We will first find the prime factorization of 88 and 38.
Prime Factorization of 88 is 1, 2, 2, 2, 11 and Prime Factorization of 38 is 1, 2, 19.
- Factorize\( (88) = \) \(1\times 2\times 2\times 2\times 11\)
- Factorize\( (38) = \) \(1\times 2\times 19\)
Now we need to find any which are common for each number (1, 2) and multiply these numbers together.
\(GCF(88, 38) = 1\times 2 = 2\).
Greatest Common Factor of 88 and 38 by matching factors method
List of positive integers factors of 88 leaving a remainder zero is 1, 2, 4, 8, 11, 22, 44, 88
List of positive integers factors of 38 leaving a remainder zero is 1, 2, 19, 38
As you can see, 2 is the greatest and common number that 88 and 38 divides into.
So the greatest common factor 88 and 38 is 2.
\(GCF(88, 38) = 2\).
