Final Step: Biggest Common Factor Number

We found the factors and prime factorization of 20 and 48. The biggest common factor number is the GCF number. So the greatest common factor 20 and 48 is 4.

Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. Common Factors of 36 and 48: 1, 2, 3, 4, 6, 12. Greatest among them is 12. Therefore, HCF of 36 and 48 is 12.

HCF or highest common factor is the factor of any two or more numbers, which are common among them. Sometimes, it is also called the greatest common factor (GCF) or greatest common divisor (GCD). For example, the HCF of 2 and 4 is 2, because 2 is the number which is common to both 2 and 4.

The 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.

We found the factors and prime factorization of 20 and 24. The biggest common factor number is the GCF number. So the greatest common factor 20 and 24 is 4.
