Greatest Common Factor of 60 and 142
GCF(60, 142) = 2, Greatest common factor of 60 and 142 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 60 and 142. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 60 and 142 by prime factorization method
We will first find the prime factorization of 60 and 142.
Prime Factorization of 60 is 1, 2, 2, 3, 5 and Prime Factorization of 142 is 1, 2, 71.
- Factorize\( (60) = \) \(1\times 2\times 2\times 3\times 5\)
- Factorize\( (142) = \) \(1\times 2\times 71\)
Now we need to find any which are common for each number (1, 2) and multiply these numbers together.
\(GCF(60, 142) = 1\times 2 = 2\).
Greatest Common Factor of 60 and 142 by matching factors method
List of positive integers factors of 60 leaving a remainder zero is 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
List of positive integers factors of 142 leaving a remainder zero is 1, 2, 71, 142
As you can see, 2 is the greatest and common number that 60 and 142 divides into.
So the greatest common factor 60 and 142 is 2.
\(GCF(60, 142) = 2\).
