The greatest common factor of 24 and 30 is 6
Method 1: Listing Factors
List 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, 12
Factors of 30: 1, 2, 3, 5, 6, 10, 15
The greatest common factor is 6.
Method 2: Prime Factorization
Find the prime factorization of each number. The prime numbers that the numbers all share multiply to the great common factor.
24=2*2*2*3
30=2*3*5
2*3=6
24 and 36 share one two and one three. Therefore, the greatest common factor is 6.
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30
The common factors are: 1, 2, 3, 6
The Greatest Common Factor (GCF) is: 6
The GCF of 30 and 24 is 6.
GCF(24, 30) = 6
