Given Input Data is 845, 400, 958, 641

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

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 400 is 2 x 2 x 2 x 2 x 5 x 5

Prime Factorization of 958 is 2 x 479

Prime Factorization of 641 is 641

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(845, 400) = 67600

GCD(845, 400) = ( 845 x 400 ) / 67600

GCD(845, 400) = 338000 / 67600

GCD(845, 400) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 958

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

LCM(5, 958) = 4790

GCD(5, 958) = ( 5 x 958 ) / 4790

GCD(5, 958) = 4790 / 4790

GCD(5, 958) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 641

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

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

GCD(1, 641) = 641 / 641

GCD(1, 641) = 1

GCD of 845, 400, 958, 641 is 1
