Greatest Common Factor of 100 and 272
GCF(100, 272) = 4, Greatest common factor of 100 and 272 is 4. 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 100 and 272. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 100 and 272 by prime factorization method
We will first find the prime factorization of 100 and 272.
Prime Factorization of 100 is 1, 2, 2, 5, 5 and Prime Factorization of 272 is 1, 2, 2, 2, 2, 17.
- Factorize\( (100) = \) \(1\times 2\times 2\times 5\times 5\)
- Factorize\( (272) = \) \(1\times 2\times 2\times 2\times 2\times 17\)
Now we need to find any which are common for each number (1, 2, 2) and multiply these numbers together.
\(GCF(100, 272) = 1\times 2\times 2 = 4\).
Greatest Common Factor of 100 and 272 by matching factors method
List of positive integers factors of 100 leaving a remainder zero is 1, 2, 4, 5, 10, 20, 25, 50, 100
List of positive integers factors of 272 leaving a remainder zero is 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
As you can see, 4 is the greatest and common number that 100 and 272 divides into.
So the greatest common factor 100 and 272 is 4.
\(GCF(100, 272) = 4\).
