Therefore, GCD of numbers 77, 805, 203, 268 is 1

Given Input Data is 77, 805, 203, 268

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 203 is 7 x 29

Prime Factorization of 268 is 2 x 2 x 67

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(77, 805) = 8855

GCD(77, 805) = ( 77 x 805 ) / 8855

GCD(77, 805) = 61985 / 8855

GCD(77, 805) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 203

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

LCM(7, 203) = 203

GCD(7, 203) = ( 7 x 203 ) / 203

GCD(7, 203) = 1421 / 203

GCD(7, 203) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 268

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

LCM(7, 268) = 1876

GCD(7, 268) = ( 7 x 268 ) / 1876

GCD(7, 268) = 1876 / 1876

GCD(7, 268) = 1

GCD of 77, 805, 203, 268 is 1
