## Greatest Common Factor of 44 and 30

GCF(44, 30) = 2, Greatest common factor of 44 and 30 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 44 and 30. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.

### Greatest Common Factor of 44 and 30 by prime factorization method

We will first find the prime factorization of 44 and 30.
Prime Factorization of 44 is 1, 2, 2, 11 and Prime Factorization of 30 is 1, 2, 3, 5.

• Factorize$$(44) =$$ $$1\times 2\times 2\times 11$$
• Factorize$$(30) =$$ $$1\times 2\times 3\times 5$$
Now we need to find any which are common for each number (1, 2) and multiply these numbers together.
$$GCF(44, 30) = 1\times 2 = 2$$.

### Greatest Common Factor of 44 and 30 by matching factors method

List of positive integers factors of 44 leaving a remainder zero is 1, 2, 4, 11, 22, 44
List of positive integers factors of 30 leaving a remainder zero is 1, 2, 3, 5, 6, 10, 15, 30
As you can see, 2 is the greatest and common number that 44 and 30 divides into.
So the greatest common factor 44 and 30 is 2.
$$GCF(44, 30) = 2$$.
