Therefore, GCD of numbers 669, 327, 257, 765 is 1

Given Input Data is 669, 327, 257, 765

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

Prime Factorization of 669 is 3 x 223

Prime Factorization of 327 is 3 x 109

Prime Factorization of 257 is 257

Prime Factorization of 765 is 3 x 3 x 5 x 17

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(669, 327) = 72921

GCD(669, 327) = ( 669 x 327 ) / 72921

GCD(669, 327) = 218763 / 72921

GCD(669, 327) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 257

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

LCM(3, 257) = 771

GCD(3, 257) = ( 3 x 257 ) / 771

GCD(3, 257) = 771 / 771

GCD(3, 257) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 765

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

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

GCD(1, 765) = 765 / 765

GCD(1, 765) = 1

GCD of 669, 327, 257, 765 is 1
