The greatest common factor of 24 and 30 is 6Method 1: Listing FactorsList all the factors of both numbers and the highest factor that is the same is the greatest common factor.Factors of 24: 1, 2, 3, 4, 6, 8, 12Factors of 30: 1, 2, 3, 5, 6, 10, 15The greatest common factor is 6.Method 2: Prime FactorizationFind the prime factorization of each number. The prime numbers that the numbers all share multiply to the great common factor.24=2*2*2*330=2*3*52*3=624 and 36 share one two and one three. Therefore, the greatest common factor is 6.
