The least common factor of any set of positive integers is 1.
The least common factor is 1. (The least common factor of any two or more positive integers is always 1.)
Greatest common factor (GCF) =7 Least common multiple (LCM) =693
You need at least two numbers to find a GCF.
The greatest common factor of 21 and 77 is 7.
The LCM is 77.
The greatest common factor of 90 , 77 = 1
The greatest common factor of 22 and 77 is 11.
The greatest common factor of 77 and 143 is 11.
94 and 77's highest common factor is one.
There is not a greatest common factor of a single number, such as 77, because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 77 are 1, 7, 11, and 77. The prime factors of 77 are 7 and 11. Examples: The greatest common factor of 63 and 77 is 7. The greatest common factor of 74 and 77 is 1. The greatest common factor of 77 and 121 is 11.
The greatest common factor of 77 and 88 is 11, and it is also the greatest prime factor.
