Therefore, GCD of numbers 660, 856, 585, 273 is 1

Given Input Data is 660, 856, 585, 273

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 856 is 2 x 2 x 2 x 107

Prime Factorization of 585 is 3 x 3 x 5 x 13

Prime Factorization of 273 is 3 x 7 x 13

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, 856) = 141240

GCD(660, 856) = ( 660 x 856 ) / 141240

GCD(660, 856) = 564960 / 141240

GCD(660, 856) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 585

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

LCM(4, 585) = 2340

GCD(4, 585) = ( 4 x 585 ) / 2340

GCD(4, 585) = 2340 / 2340

GCD(4, 585) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 273

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

LCM(1, 273) = 273

GCD(1, 273) = ( 1 x 273 ) / 273

GCD(1, 273) = 273 / 273

GCD(1, 273) = 1

GCD of 660, 856, 585, 273 is 1
