Given Input Data is 74, 784, 190, 515

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

Prime Factorization of 74 is 2 x 37

Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 515 is 5 x 103

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(74, 784) = 29008

GCD(74, 784) = ( 74 x 784 ) / 29008

GCD(74, 784) = 58016 / 29008

GCD(74, 784) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 190

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

LCM(2, 190) = 190

GCD(2, 190) = ( 2 x 190 ) / 190

GCD(2, 190) = 380 / 190

GCD(2, 190) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 515

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

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

GCD(2, 515) = 1030 / 1030

GCD(2, 515) = 1

GCD of 74, 784, 190, 515 is 1
