The factors of 45 are:
1, 3, 5, 9, 15, 45
The factors of 81 are:
1, 3, 9, 27, 81
The common factors are:
1, 3, 9
The highest common factor of 81 and 63 is 9
The GCF is 9.
Use the following factor trees to determine the answer355, 7and637, 97, 3, 37 is the common factor of 35 and 63
The greatest common factor of 56 and 81 is 1.
The GCF of 53 and 81 is 1.
The highest common factor of 81 and 63 is 9
The Greatest Common Factor (GCF) is: 9
The GCF is 9.
The GCF is 9.
9
The GCF is 9.
The greatest common factor of 63, 81, and 99 is 9.The prime factorization of 63 is 7*9.The prime factorization of 81 is 9*9.The prime factorization of 99 is 11*9.Thus, the greatest of the common factors of 9.
The GCF is 9
The GCF is 9.
If that's 81 and 63, the GCF is 9.
The GCF is 1.
Factors of 63: 1, 3, 7, 9, 21 and 63.Factors of 81: 1, 3, 9, 27 and 81.Common factors are 1, 3 and 9.And another method is by finding the GCF of 63 and 81.The factors of GCF are the common factors of 63 and 81.GCF of 63 and 81 is 9. And factors of 9 are 1, 3 and 9.Instead of writing all factors of 63 and 81 it is better to find GCF and then its factors.
