The greatest common factor is 2. Now, look back at the two lists and see if any of the numbers are the same in both lists. If there is more than one, the greatest number will be the greatest common factor. In this case, the only common number is 2, and so it is automatically the greatest common factor. Both 4 and 10 are even, so they must have a common factor of 2. In this case this is the only common factor apart from 1.
Any non zero whole number times 0 equals 0 so it is true that every non zero whole number is a factor of 0. In this example, 5 and 0 are factors of 0. There are several ways to find the greatest common factor of numbers. The most efficient method you use depends on how many numbers you have, how large they are and what you will do with the result. To find the GCF by factoring, list out all of the factors of each number or find them with a Factors Calculator. The whole number factors are numbers that divide evenly into the number with zero remainder. Given the list of common factors for each number, the GCF is the largest number common to each list.
The prime factorization calculator will take any number and find its prime factors. Simply type the number into our tool and in no time you'll find the prime factorization. To understand the whole process, first you must get familiar with what is a prime factor. Once you understand that, we will move on to the difference between prime factor and prime factorization. Below, you'll find all the answers, as well as concise information about how to find prime factorization and what a factor tree is.
Now, look back at the two lists and see if any of the numbers are the same in both lists. Both 4 and 10 are even, so they must have a common factor of 2. and roots is to write each number as the product of its prime factors.

Every whole number greater than 1 has a prime factorization — that is, the list of prime numbers including repeats that equal that number when multiplied together. For example, here are the prime factorizations of 14, 20, and Factor trees are a useful tool for finding the prime factorization of a number. For example, to find the prime factorization 30, first find a factor pair — a pair of numbers that, when multiplied together, equals But 10 is not prime, so you can continue the tree, finding a factor pair for You can use prime factorization to find the greatest common factor GCF of a set of numbers.
