1, 577
Greatest Common Divisior
We found the divisors of 861, 980, 577 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 861, 980, 577 is 1.
Therefore, GCD of numbers 861, 980, 577 is 1
Given Input Data is 861, 980, 577
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 861 is 3 x 7 x 41
Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7
Prime Factorization of 577 is 577
The above numbers do not have any common prime factor. So GCD is 1
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(861, 980) = 120540
GCD(861, 980) = ( 861 x 980 ) / 120540
GCD(861, 980) = 843780 / 120540
GCD(861, 980) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 577
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 577) = 4039
GCD(7, 577) = ( 7 x 577 ) / 4039
GCD(7, 577) = 4039 / 4039
GCD(7, 577) = 1
GCD of 861, 980, 577 is 1
