Greatest Common Factor (GCF) of 2, 4 and 15
We here at the Fraction Calculator often determine the Greatest Common Factor (GCF) for numbers such as 2, 4 and 15, because we use the GCF to lower the denominators of our fractions.
The Greatest Common Factor of 2, 4 and 15 is the greatest number (factor) that you can evenly divide 2, 4 and 15 by.
To find the Greatest Common Factor of 2, 4 and 15, we first have to identify all the factors of each number. Then we see which factors they have in common, and finally we pick the largest number they have in common, which is the Greatest Common Factor (GCF) of 2, 4 and 15.
The factors of 2 are 1 and 2. The factors of 4 are 1, 2, and 4. The factors of 15 are 1, 3, 5, and 15. The highest factor they have in common is 1. Therefore, the Greatest Common Factor (GCF) of 2, 4 and 15 is as follows:
GCF(2,4,15) = 1
