Given Input Data is 87, 792, 455, 181

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

Prime Factorization of 87 is 3 x 29

Prime Factorization of 792 is 2 x 2 x 2 x 3 x 3 x 11

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 181 is 181

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(87, 792) = 22968

GCD(87, 792) = ( 87 x 792 ) / 22968

GCD(87, 792) = 68904 / 22968

GCD(87, 792) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 455

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

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

GCD(3, 455) = 1365 / 1365

GCD(3, 455) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 181

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

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

GCD(1, 181) = 181 / 181

GCD(1, 181) = 1

GCD of 87, 792, 455, 181 is 1
