Therefore, GCD of numbers 764, 432, 80, 649 is 1

Given Input Data is 764, 432, 80, 649

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

Prime Factorization of 764 is 2 x 2 x 191

Prime Factorization of 432 is 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 649 is 11 x 59

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(764, 432) = 82512

GCD(764, 432) = ( 764 x 432 ) / 82512

GCD(764, 432) = 330048 / 82512

GCD(764, 432) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 80

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

LCM(4, 80) = 80

GCD(4, 80) = ( 4 x 80 ) / 80

GCD(4, 80) = 320 / 80

GCD(4, 80) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 649

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

LCM(4, 649) = 2596

GCD(4, 649) = ( 4 x 649 ) / 2596

GCD(4, 649) = 2596 / 2596

GCD(4, 649) = 1

GCD of 764, 432, 80, 649 is 1
