Given Input Data is 843, 786, 200, 247

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

Prime Factorization of 843 is 3 x 281

Prime Factorization of 786 is 2 x 3 x 131

Prime Factorization of 200 is 2 x 2 x 2 x 5 x 5

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(843, 786) = 220866

GCD(843, 786) = ( 843 x 786 ) / 220866

GCD(843, 786) = 662598 / 220866

GCD(843, 786) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 200

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

LCM(3, 200) = 600

GCD(3, 200) = ( 3 x 200 ) / 600

GCD(3, 200) = 600 / 600

GCD(3, 200) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 247

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

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

GCD(1, 247) = 247 / 247

GCD(1, 247) = 1

GCD of 843, 786, 200, 247 is 1
