Therefore, GCD of numbers 781, 348, 122 is 1

Given Input Data is 781, 348, 122

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

Prime Factorization of 781 is 11 x 71

Prime Factorization of 348 is 2 x 2 x 3 x 29

Prime Factorization of 122 is 2 x 61

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(781, 348) = 271788

GCD(781, 348) = ( 781 x 348 ) / 271788

GCD(781, 348) = 271788 / 271788

GCD(781, 348) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 122

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

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

GCD(1, 122) = 122 / 122

GCD(1, 122) = 1

GCD of 781, 348, 122 is 1
