GCF of 78, 42, 94, 883

Given numbers are 78, 42, 94, 883
The greatest common factor of 78, 42, 94, 883 can be found by using the following 2 different methods.
The GCF of 78, 42, 94, 883 is 1.

Prime factorization is basically division by prime numbers only. Keep dividing all numbers by the same prime number, until the numbers can no longer be divided by a single prime number. Then, multiply all the prime numbers that are on the left side.

∴ GCF of numbers is 1 because of no common factors present between them.

The common factor method requires listing down all the factors of 78,42,94,883 that divide each of these numbers without leaving a remainder. To begin, let us list down the factors
