Therefore, GCD of numbers 660, 918, 570, 605 is 1

Given Input Data is 660, 918, 570, 605

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

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 918 is 2 x 3 x 3 x 3 x 17

Prime Factorization of 570 is 2 x 3 x 5 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(660, 918) = 100980

GCD(660, 918) = ( 660 x 918 ) / 100980

GCD(660, 918) = 605880 / 100980

GCD(660, 918) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 570

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

LCM(6, 570) = 570

GCD(6, 570) = ( 6 x 570 ) / 570

GCD(6, 570) = 3420 / 570

GCD(6, 570) = 6

Step3:

Here we consider the GCD from the above i.e. 6 as first number and the next as 605

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

LCM(6, 605) = 3630

GCD(6, 605) = ( 6 x 605 ) / 3630

GCD(6, 605) = 3630 / 3630

GCD(6, 605) = 1

GCD of 660, 918, 570, 605 is 1
