Therefore, GCD of numbers 673, 797, 206, 642 is 1

Given Input Data is 673, 797, 206, 642

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

Prime Factorization of 673 is 673

Prime Factorization of 797 is 797

Prime Factorization of 206 is 2 x 103

Prime Factorization of 642 is 2 x 3 x 107

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(673, 797) = 536381

GCD(673, 797) = ( 673 x 797 ) / 536381

GCD(673, 797) = 536381 / 536381

GCD(673, 797) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 206

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

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

GCD(1, 206) = 206 / 206

GCD(1, 206) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 642

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

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

GCD(1, 642) = 642 / 642

GCD(1, 642) = 1

GCD of 673, 797, 206, 642 is 1
