Therefore, GCD of numbers 323, 266, 287, 661 is 1

Given Input Data is 323, 266, 287, 661

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

Prime Factorization of 323 is 17 x 19

Prime Factorization of 266 is 2 x 7 x 19

Prime Factorization of 287 is 7 x 41

Prime Factorization of 661 is 661

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(323, 266) = 4522

GCD(323, 266) = ( 323 x 266 ) / 4522

GCD(323, 266) = 85918 / 4522

GCD(323, 266) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 287

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

LCM(19, 287) = 5453

GCD(19, 287) = ( 19 x 287 ) / 5453

GCD(19, 287) = 5453 / 5453

GCD(19, 287) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 661

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

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

GCD(1, 661) = 661 / 661

GCD(1, 661) = 1

GCD of 323, 266, 287, 661 is 1
