Given Input Data is 170, 122, 655, 587

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

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 122 is 2 x 61

Prime Factorization of 655 is 5 x 131

Prime Factorization of 587 is 587

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(170, 122) = 10370

GCD(170, 122) = ( 170 x 122 ) / 10370

GCD(170, 122) = 20740 / 10370

GCD(170, 122) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 655

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

LCM(2, 655) = 1310

GCD(2, 655) = ( 2 x 655 ) / 1310

GCD(2, 655) = 1310 / 1310

GCD(2, 655) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 587

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

LCM(1, 587) = 587

GCD(1, 587) = ( 1 x 587 ) / 587

GCD(1, 587) = 587 / 587

GCD(1, 587) = 1

GCD of 170, 122, 655, 587 is 1
