One way to determine the greatest common factor is to find all the factors of the numbers and compare them.
The factors of 142 are 1, 2, 71, and 142.
The factors of 231 are 1, 3, 7, 11, 21, 33, 77, and 231.
The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.
The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.
The prime factors of 142 are 2 and 71.
The prime factors of 231 are 3, 7, and 11.
There are no prime factors in common, so the numbers are relatively prime, meaning the greatest common factor is 1.
The greatest common factor of 231 and 154 is 77.
The greatest common factor (GCF) of 121 and 231 is 11.
21
GCF(60, 231) = 3.
The GCF is 11.
The GCF is 1.
The Greatest Common Factor is 33
The GCF is 33.
The GCF is: 77
33
The GCF is 3.
The GCF is 3.
