Given Input Data is 770, 854, 156, 247

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

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 854 is 2 x 7 x 61

Prime Factorization of 156 is 2 x 2 x 3 x 13

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(770, 854) = 46970

GCD(770, 854) = ( 770 x 854 ) / 46970

GCD(770, 854) = 657580 / 46970

GCD(770, 854) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 156

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

LCM(14, 156) = 1092

GCD(14, 156) = ( 14 x 156 ) / 1092

GCD(14, 156) = 2184 / 1092

GCD(14, 156) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 247

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

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

GCD(2, 247) = 494 / 494

GCD(2, 247) = 1

GCD of 770, 854, 156, 247 is 1
