Given Input Data is 456, 978, 29, 740

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

Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 29 is 29

Prime Factorization of 740 is 2 x 2 x 5 x 37

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(456, 978) = 74328

GCD(456, 978) = ( 456 x 978 ) / 74328

GCD(456, 978) = 445968 / 74328

GCD(456, 978) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 29

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

LCM(6, 29) = 174

GCD(6, 29) = ( 6 x 29 ) / 174

GCD(6, 29) = 174 / 174

GCD(6, 29) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 740

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

LCM(1, 740) = 740

GCD(1, 740) = ( 1 x 740 ) / 740

GCD(1, 740) = 740 / 740

GCD(1, 740) = 1

GCD of 456, 978, 29, 740 is 1
