Given Input Data is 808, 393, 61, 907

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

Prime Factorization of 808 is 2 x 2 x 2 x 101

Prime Factorization of 393 is 3 x 131

Prime Factorization of 61 is 61

Prime Factorization of 907 is 907

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(808, 393) = 317544

GCD(808, 393) = ( 808 x 393 ) / 317544

GCD(808, 393) = 317544 / 317544

GCD(808, 393) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 907

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

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

GCD(1, 907) = 907 / 907

GCD(1, 907) = 1

GCD of 808, 393, 61, 907 is 1
