So the Greatest Common Divisior 771, 122, 126 is 1.

Therefore, GCD of numbers 771, 122, 126 is 1

Given Input Data is 771, 122, 126

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 771 is 3 x 257

Prime Factorization of 122 is 2 x 61

Prime Factorization of 126 is 2 x 3 x 3 x 7

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(771, 122) = 94062

GCD(771, 122) = ( 771 x 122 ) / 94062

GCD(771, 122) = 94062 / 94062

GCD(771, 122) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 126

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

GCD(1, 126) = 126 / 126

GCD(1, 126) = 1

GCD of 771, 122, 126 is 1
