Therefore, GCD of numbers 99, 381, 387, 247 is 1

Given Input Data is 99, 381, 387, 247

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

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 381 is 3 x 127

Prime Factorization of 387 is 3 x 3 x 43

Prime Factorization of 247 is 13 x 19

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(99, 381) = 12573

GCD(99, 381) = ( 99 x 381 ) / 12573

GCD(99, 381) = 37719 / 12573

GCD(99, 381) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 387

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

LCM(3, 387) = 387

GCD(3, 387) = ( 3 x 387 ) / 387

GCD(3, 387) = 1161 / 387

GCD(3, 387) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 247

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

LCM(3, 247) = 741

GCD(3, 247) = ( 3 x 247 ) / 741

GCD(3, 247) = 741 / 741

GCD(3, 247) = 1

GCD of 99, 381, 387, 247 is 1
