Given Input Data is 640, 465, 849

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

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 465 is 3 x 5 x 31

Prime Factorization of 849 is 3 x 283

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(640, 465) = 59520

GCD(640, 465) = ( 640 x 465 ) / 59520

GCD(640, 465) = 297600 / 59520

GCD(640, 465) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 849

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

LCM(5, 849) = 4245

GCD(5, 849) = ( 5 x 849 ) / 4245

GCD(5, 849) = 4245 / 4245

GCD(5, 849) = 1

GCD of 640, 465, 849 is 1
