So the Greatest Common Divisior 129, 383, 620, 949 is 1.

Therefore, GCD of numbers 129, 383, 620, 949 is 1

Given Input Data is 129, 383, 620, 949

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

Prime Factorization of 129 is 3 x 43

Prime Factorization of 383 is 383

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 949 is 13 x 73

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(129, 383) = 49407

GCD(129, 383) = ( 129 x 383 ) / 49407

GCD(129, 383) = 49407 / 49407

GCD(129, 383) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 620

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

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

GCD(1, 620) = 620 / 620

GCD(1, 620) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 949

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

LCM(1, 949) = 949

GCD(1, 949) = ( 1 x 949 ) / 949

GCD(1, 949) = 949 / 949

GCD(1, 949) = 1

GCD of 129, 383, 620, 949 is 1
