The HCF of both numbers is 1
3
9 is both a factor and multiple of 9, since 1*9 = 9.
Common factors have to go into both numbers. The only common factor of 20 and 27 is 1.
the greatest common factor for 27 and 32 is 1
The common factors of 27 and 81 are: 1, 3, 9, and 27
They only have one common factor: 1
The common factor of both 15 and 27 is 3.
The GCF is 3 because for factor for 78 is 1,2,3,6,13,26,39,78 and factor for 27 is 1,3,9,27 and they both have 3 in common so the answer will be 3

1 and 3, are both the common factors and the GCF of 15 and 27.
The greatest common factor of 81 and 27 is 27. You can only divide 27 by 1, 3, 9, and 27. You can only divide 81 by 1, 3, 9, 27, and 81. 27 is the biggest factor that both of the numbers have.
