Given Input Data is 156, 918, 61, 247

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

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

Prime Factorization of 918 is 2 x 3 x 3 x 3 x 17

Prime Factorization of 61 is 61

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(156, 918) = 23868

GCD(156, 918) = ( 156 x 918 ) / 23868

GCD(156, 918) = 143208 / 23868

GCD(156, 918) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 61

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

LCM(6, 61) = 366

GCD(6, 61) = ( 6 x 61 ) / 366

GCD(6, 61) = 366 / 366

GCD(6, 61) = 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 156, 918, 61, 247 is 1
