Given Input Data is 855, 666, 65, 529

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

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 666 is 2 x 3 x 3 x 37

Prime Factorization of 65 is 5 x 13

Prime Factorization of 529 is 23 x 23

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(855, 666) = 63270

GCD(855, 666) = ( 855 x 666 ) / 63270

GCD(855, 666) = 569430 / 63270

GCD(855, 666) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 65

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

LCM(9, 65) = 585

GCD(9, 65) = ( 9 x 65 ) / 585

GCD(9, 65) = 585 / 585

GCD(9, 65) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 529

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

LCM(1, 529) = 529

GCD(1, 529) = ( 1 x 529 ) / 529

GCD(1, 529) = 529 / 529

GCD(1, 529) = 1

GCD of 855, 666, 65, 529 is 1
