The greatest common factor of 45 and 63 is 9.
63 is the HCF
The greatest common factor of 63 and 147 is 21.
The common factors are: 1, 3 The Greatest Common Factor (GCF) is: 3

It is 3
factors of 567 = 3x3x3x3x7 factors of 441=3x3x7x7 so common factors among the two numbers are= 3x3x7 so the greatest common factor is =63
Yes, two odd numbers can have a greatest common factor of 1 if they have no factors in common. For example, 5 and 7 have a GCF of 1, as do 63 and 55.
The greatest common factor is 9
Factors of 15 are 1, 3, 5, and 15. Factors of 63 are 1, 3, 7, 9, 21, and 63. The greatest common factor of 15 and 63 is 3.
The GCF is 63.
