The common factors of 54 and 63 are: 1, 3, and 9
The common factors of 45 and 63 are 1, 3, and 9.
The GCF of 54 and 63 is 9 The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. The factors of 63 are 1, 3, 7, 9, 21, and 63. The factors they have in common are 1, 3, and 9. Therefore, 9 is the greatest common factor. The factors can also be determined from the prime factors. The prime factors of 54 are 2, 3, 3, and 3. The prime factors of 63 are 3, 3, and 7. The prime factors they have in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.

The factors of 54 are:1, 2, 3, 6, 9, 18, 27, 54The factors of 63 are:1, 3, 7, 9, 21, 63The common factors are: 1, 3, 9The Greatest Common Factor (GCF) is: 9
The GCF of 18 and 63 is 9.The factors of 63 are: 1, 3, 7, 9, 21, & 63The factors of 18 are: 1, 2, 3, 6, 9, & 18The GCF (AKA Greatest Common Factor) is 9.Using prime factorization for 18 you get 2, and two 3's as your primes. For 63 you get 7, and two 3's as your primes. As the two 3's are in common you between both of the numbers, you do 3 multiplied by 3 which is 9. Therefore the gcf for 18, and 63 is 9.The GCF is 9.
The factors of 63 are 1, 3, 7, 9, 21 and 63. For them to be common, they need to be compared to another set of factors.
The common factors of 54 and 63 are: 1, 3, and 9
