Therefore, GCD of numbers 396, 784, 73, 856 is 1

Given Input Data is 396, 784, 73, 856

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

Prime Factorization of 396 is 2 x 2 x 3 x 3 x 11

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

Prime Factorization of 73 is 73

Prime Factorization of 856 is 2 x 2 x 2 x 107

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(396, 784) = 77616

GCD(396, 784) = ( 396 x 784 ) / 77616

GCD(396, 784) = 310464 / 77616

GCD(396, 784) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 73

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

LCM(4, 73) = 292

GCD(4, 73) = ( 4 x 73 ) / 292

GCD(4, 73) = 292 / 292

GCD(4, 73) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 856

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

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

GCD(1, 856) = 856 / 856

GCD(1, 856) = 1

GCD of 396, 784, 73, 856 is 1
