Therefore, GCD of numbers 385, 308, 97, 787 is 1

Given Input Data is 385, 308, 97, 787

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

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 308 is 2 x 2 x 7 x 11

Prime Factorization of 97 is 97

Prime Factorization of 787 is 787

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(385, 308) = 1540

GCD(385, 308) = ( 385 x 308 ) / 1540

GCD(385, 308) = 118580 / 1540

GCD(385, 308) = 77

Step2:

Here we consider the GCD from the above i.e. 77 as first number and the next as 97

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

LCM(77, 97) = 7469

GCD(77, 97) = ( 77 x 97 ) / 7469

GCD(77, 97) = 7469 / 7469

GCD(77, 97) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 787

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

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

GCD(1, 787) = 787 / 787

GCD(1, 787) = 1

GCD of 385, 308, 97, 787 is 1
