Greatest common factor of 77 and 121 is 11.
Greater than what? As every number has a factor of 1, there is always a common factor of 1 between any two numbers; if there are no other common factors then the greatest common factor of those numbers is 1. The factors of 154 and 42 are: 154: 1, 2, 7, 11, 14, 22, 77, 154 42: 1, 2, 3, 6, 7, 14, 21, 42 Their common factors are: 1, 2, 7, 14 Therefore their greatest common factor is 14.
The only common factor is 1.
The factors of 77 are 1, 7, 11, 77. For them to be common, they need to be compared to another set of factors.
Just look for common factors, and divide both numbers by that common factor.7 is a common factor, so 77/147 = 11/21.
The greatest common factor of 42, 77 and 84 is 7.
the answer is 7

The GCF is 7.
The least common factor is 1. (The least common factor of any two or more positive integers is always 1.)
The least common factor of any set of numbers is 1.
The GCF is 7.
