Greatest Common Factor (GCF) of 2, 4 and 90
We here at the Fraction Calculator often determine the Greatest Common Factor (GCF) for numbers such as 2, 4 and 90, because we use the GCF to lower the denominators of our fractions.
The Greatest Common Factor of 2, 4 and 90 is the greatest number (factor) that you can evenly divide 2, 4 and 90 by.
To find the Greatest Common Factor of 2, 4 and 90, 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 90.
The factors of 2 are 1 and 2. The factors of 4 are 1, 2, and 4. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The highest factor they have in common is 2. Therefore, the Greatest Common Factor (GCF) of 2, 4 and 90 is as follows:
GCF(2,4,90) = 2
