Therefore, GCD of numbers 771, 321, 515, 623 is 1

Given Input Data is 771, 321, 515, 623

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

Prime Factorization of 771 is 3 x 257

Prime Factorization of 321 is 3 x 107

Prime Factorization of 515 is 5 x 103

Prime Factorization of 623 is 7 x 89

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(771, 321) = 82497

GCD(771, 321) = ( 771 x 321 ) / 82497

GCD(771, 321) = 247491 / 82497

GCD(771, 321) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 515

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

LCM(3, 515) = 1545

GCD(3, 515) = ( 3 x 515 ) / 1545

GCD(3, 515) = 1545 / 1545

GCD(3, 515) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 623

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

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

GCD(1, 623) = 623 / 623

GCD(1, 623) = 1

GCD of 771, 321, 515, 623 is 1
