Given Input Data is 768, 492, 993, 640

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

Prime Factorization of 768 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime Factorization of 492 is 2 x 2 x 3 x 41

Prime Factorization of 993 is 3 x 331

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

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(768, 492) = 31488

GCD(768, 492) = ( 768 x 492 ) / 31488

GCD(768, 492) = 377856 / 31488

GCD(768, 492) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 993

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

LCM(12, 993) = 3972

GCD(12, 993) = ( 12 x 993 ) / 3972

GCD(12, 993) = 11916 / 3972

GCD(12, 993) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 640

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

LCM(3, 640) = 1920

GCD(3, 640) = ( 3 x 640 ) / 1920

GCD(3, 640) = 1920 / 1920

GCD(3, 640) = 1

GCD of 768, 492, 993, 640 is 1
