Put simply, the GCF of a set of whole numbers is the largest positive integer (i.e whole number and not a decimal) … WebPrime Factors for 6: 2 and 3. Prime Factors for 15: 3 and 5. Now that we have the list of prime factors, we need to find any which are common for each number. In this case, there is only one common prime factor, 3. Since there are no others, the greatest common factor is this prime factor: GCF = 3.
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 Greatest Common Factor, the GCF, is the biggest (that is, the "greatest") number that will divide into (that is, the largest number that is a factor of) both 2940 and 3150. In other words, it's the number that contains all the factors *common* to both numbers. In this case, the GCF is the product of all the factors that 2940 and 3150 share.
