Are you looking for a way to calculate the greatest common factor of 120, 880 ? Well, you’re in luck! In this article, we will be showing you how to use two different methods to find the GCF of 120, 880. We also provide a free GCF of Two or More Numbers Calculator to obtain instant results.
Given numbers are 120, 880
The greatest common factor of 120, 880 can be found by using the following 2 different methods.
The GCF of 120, 880 is 40.
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.
2 | 120, 880 |
2 | 60, 440 |
2 | 30, 220 |
5 | 15, 110 |
3, 22 |
∴ Thus, the GCF of given numbers is 2 x 2 x 2 x 5 = 40
The common factor method requires listing down all the factors of 120,880 that divide each of these numbers without leaving a remainder. To begin, let us list down the factors
