Step-by-step explanation:
The factors of 36 are
1, 2, 3, 4, 6, 9, 12, 18, and 36.
The factors of 54 are
1, 2, 3, 6, 9, 18, 27, and 54.
The common factors of 36 and 54 are
1, 2, 3, 6, 9, 18
Although the numbers in bold are all common factors of both 36 and 54, 18 is the greatest common factor.
The second method to find the greatest common factor is to list the prime factors, then multiply the common prime factors.
Let’s use the same numbers, 36 and 54 again to find their greatest common factor.
Example:
The prime factorization of 36 is
2 x 2 x 3 x 3
The prime factorization of 54 is
2 x 3 x 3 x 3
