Therefore, GCD of numbers 849, 639, 757, 122 is 1

Given Input Data is 849, 639, 757, 122

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

Prime Factorization of 849 is 3 x 283

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 757 is 757

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(849, 639) = 180837

GCD(849, 639) = ( 849 x 639 ) / 180837

GCD(849, 639) = 542511 / 180837

GCD(849, 639) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 757

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

LCM(3, 757) = 2271

GCD(3, 757) = ( 3 x 757 ) / 2271

GCD(3, 757) = 2271 / 2271

GCD(3, 757) = 1

Step3:

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 849, 639, 757, 122 is 1
