WebThe greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators. Created by Sal Khan. Sort by: Top Voted Questions Tips & Thanks WebThe biggest common factor number is the GCF number. So the Greatest Common Factor 12, 20, 28 is 4. Therefore, GCF of numbers 12, 20, 28 is 4 Finding GCF of 12, 20, 28 using Prime Factorization Given Input Data is 12, 20, 28 Make a list of Prime Factors of all the given numbers initially Prime Factorization of 12 is 2 x 2 x 3

WebGCF of 14 and 28 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. Step 1: Divide 28 (larger number) by 14 (smaller number). Step 2: Since the remainder = 0, the divisor (14) is the GCF of 14 and 28. The corresponding divisor (14) is the GCF of 14 and 28. WebGreatest common factors are most often used when reducing fractions. It would be applied like this: Reduce 15/20. First, you would list the factors of both 15 and 20, like this: 15: 1, 3, 5, 15. 20: 1, 2, 4, 5, 10, 20. Now, you would underline the common factors between the two numbers, like this: 15: 1, 3, 5, 15. 20: 1, 2, 4, 5, 10, 20.
