Therefore, GCD of numbers 68, 164, 398, 773 is 1

Given Input Data is 68, 164, 398, 773

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

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 164 is 2 x 2 x 41

Prime Factorization of 398 is 2 x 199

Prime Factorization of 773 is 773

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(68, 164) = 2788

GCD(68, 164) = ( 68 x 164 ) / 2788

GCD(68, 164) = 11152 / 2788

GCD(68, 164) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 398

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

LCM(4, 398) = 796

GCD(4, 398) = ( 4 x 398 ) / 796

GCD(4, 398) = 1592 / 796

GCD(4, 398) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 773

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

LCM(2, 773) = 1546

GCD(2, 773) = ( 2 x 773 ) / 1546

GCD(2, 773) = 1546 / 1546

GCD(2, 773) = 1

GCD of 68, 164, 398, 773 is 1
