Therefore, GCD of numbers 55, 627, 345, 487 is 1

Given Input Data is 55, 627, 345, 487

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

Prime Factorization of 55 is 5 x 11

Prime Factorization of 627 is 3 x 11 x 19

Prime Factorization of 345 is 3 x 5 x 23

Prime Factorization of 487 is 487

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(55, 627) = 3135

GCD(55, 627) = ( 55 x 627 ) / 3135

GCD(55, 627) = 34485 / 3135

GCD(55, 627) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 345

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

LCM(11, 345) = 3795

GCD(11, 345) = ( 11 x 345 ) / 3795

GCD(11, 345) = 3795 / 3795

GCD(11, 345) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 487

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

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

GCD(1, 487) = 487 / 487

GCD(1, 487) = 1

GCD of 55, 627, 345, 487 is 1
