Therefore, GCD of numbers 86, 644, 927, 397 is 1

Given Input Data is 86, 644, 927, 397

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

Prime Factorization of 86 is 2 x 43

Prime Factorization of 644 is 2 x 2 x 7 x 23

Prime Factorization of 927 is 3 x 3 x 103

Prime Factorization of 397 is 397

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(86, 644) = 27692

GCD(86, 644) = ( 86 x 644 ) / 27692

GCD(86, 644) = 55384 / 27692

GCD(86, 644) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 927

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

LCM(2, 927) = 1854

GCD(2, 927) = ( 2 x 927 ) / 1854

GCD(2, 927) = 1854 / 1854

GCD(2, 927) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 397

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

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

GCD(1, 397) = 397 / 397

GCD(1, 397) = 1

GCD of 86, 644, 927, 397 is 1
