Given Input Data is 868, 155, 23, 283

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

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 155 is 5 x 31

Prime Factorization of 23 is 23

Prime Factorization of 283 is 283

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(868, 155) = 4340

GCD(868, 155) = ( 868 x 155 ) / 4340

GCD(868, 155) = 134540 / 4340

GCD(868, 155) = 31

Step2:

Here we consider the GCD from the above i.e. 31 as first number and the next as 23

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

LCM(31, 23) = 713

GCD(31, 23) = ( 31 x 23 ) / 713

GCD(31, 23) = 713 / 713

GCD(31, 23) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 283

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

LCM(1, 283) = 283

GCD(1, 283) = ( 1 x 283 ) / 283

GCD(1, 283) = 283 / 283

GCD(1, 283) = 1

GCD of 868, 155, 23, 283 is 1
