Given Input Data is 640, 836, 604, 465

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 836 is 2 x 2 x 11 x 19

Prime Factorization of 604 is 2 x 2 x 151

Prime Factorization of 465 is 3 x 5 x 31

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, 836) = 133760

GCD(640, 836) = ( 640 x 836 ) / 133760

GCD(640, 836) = 535040 / 133760

GCD(640, 836) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 604

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

LCM(4, 604) = 604

GCD(4, 604) = ( 4 x 604 ) / 604

GCD(4, 604) = 2416 / 604

GCD(4, 604) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 465

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

LCM(4, 465) = 1860

GCD(4, 465) = ( 4 x 465 ) / 1860

GCD(4, 465) = 1860 / 1860

GCD(4, 465) = 1

GCD of 640, 836, 604, 465 is 1
