Therefore, GCD of numbers 655, 265, 76, 605 is 1

Given Input Data is 655, 265, 76, 605

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

Prime Factorization of 655 is 5 x 131

Prime Factorization of 265 is 5 x 53

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 605 is 5 x 11 x 11

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(655, 265) = 34715

GCD(655, 265) = ( 655 x 265 ) / 34715

GCD(655, 265) = 173575 / 34715

GCD(655, 265) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 76

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

LCM(5, 76) = 380

GCD(5, 76) = ( 5 x 76 ) / 380

GCD(5, 76) = 380 / 380

GCD(5, 76) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 605

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

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

GCD(1, 605) = 605 / 605

GCD(1, 605) = 1

GCD of 655, 265, 76, 605 is 1
