(Read how to find All the Factors of a Number. Underline the factors that all the original numbers have in common. Greatest Common Factor can be estimated with the use of LCM. Greatest Common Factor of 76, 28, and 104. For 10 and 21, the greatest common factor is 1. Should I make the test easy, medium or hard? So the greatest common factor 91 and 104 is 13. In this example, 5 and 0 are factors of 0. Put simply, the GCF of a set of whole numbers is the largest positive integer (i.e whole number and not a decimal) that divides evenly into all of the numbers in the set. In order to find the greatest common factor of two numbers, you'll need to factor out both of those numbers using your knowledge of timetables, then identify the largest number that appears in both sets of factors. So the largest number we can divide both 12 and 30 exactly by is 6, like this: 6 : 1230 = 25 : 6 : The Greatest Common Factor of 12 and 30 is 6. You can find the GCF in two ways.
