Therefore, GCD of numbers 30, 297, 373, 842 is 1

Given Input Data is 30, 297, 373, 842

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 297 is 3 x 3 x 3 x 11

Prime Factorization of 373 is 373

Prime Factorization of 842 is 2 x 421

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(30, 297) = 2970

GCD(30, 297) = ( 30 x 297 ) / 2970

GCD(30, 297) = 8910 / 2970

GCD(30, 297) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 373

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

LCM(3, 373) = 1119

GCD(3, 373) = ( 3 x 373 ) / 1119

GCD(3, 373) = 1119 / 1119

GCD(3, 373) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 842

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

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

GCD(1, 842) = 842 / 842

GCD(1, 842) = 1

GCD of 30, 297, 373, 842 is 1
