Given Input Data is 244, 392, 343, 387

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

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 343 is 7 x 7 x 7

Prime Factorization of 387 is 3 x 3 x 43

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(244, 392) = 23912

GCD(244, 392) = ( 244 x 392 ) / 23912

GCD(244, 392) = 95648 / 23912

GCD(244, 392) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 343

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

LCM(4, 343) = 1372

GCD(4, 343) = ( 4 x 343 ) / 1372

GCD(4, 343) = 1372 / 1372

GCD(4, 343) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 387

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

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

GCD(1, 387) = 387 / 387

GCD(1, 387) = 1

GCD of 244, 392, 343, 387 is 1
