The GCF is 9.
The GCF of 27 and 81 is 27. And their LCM is 81.
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.
The GCF is 27.
The GCF is 27.
27 and 81, respectively.
The Greatest Common Factor (GCF) of 27, 81, and 54 is 27.
The GCF is 9.
The GCF is 9.
The GCF is 27.
The greatest common factor for the numbers 27 and 81 are 27.
The GCF of 27, 54, and 81 is 27. Since 27 is a factor of 54 and 81, it's automatically the GCF.
