Therefore, GCD of numbers 258, 303, 628, 691 is 1

Given Input Data is 258, 303, 628, 691

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

Prime Factorization of 258 is 2 x 3 x 43

Prime Factorization of 303 is 3 x 101

Prime Factorization of 628 is 2 x 2 x 157

Prime Factorization of 691 is 691

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(258, 303) = 26058

GCD(258, 303) = ( 258 x 303 ) / 26058

GCD(258, 303) = 78174 / 26058

GCD(258, 303) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 628

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

LCM(3, 628) = 1884

GCD(3, 628) = ( 3 x 628 ) / 1884

GCD(3, 628) = 1884 / 1884

GCD(3, 628) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 691

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

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

GCD(1, 691) = 691 / 691

GCD(1, 691) = 1

GCD of 258, 303, 628, 691 is 1
