Therefore, GCD of numbers 18, 402, 191, 494 is 1

Given Input Data is 18, 402, 191, 494

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 191 is 191

Prime Factorization of 494 is 2 x 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(18, 402) = 1206

GCD(18, 402) = ( 18 x 402 ) / 1206

GCD(18, 402) = 7236 / 1206

GCD(18, 402) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 191

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

LCM(6, 191) = 1146

GCD(6, 191) = ( 6 x 191 ) / 1146

GCD(6, 191) = 1146 / 1146

GCD(6, 191) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 494

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

LCM(1, 494) = 494

GCD(1, 494) = ( 1 x 494 ) / 494

GCD(1, 494) = 494 / 494

GCD(1, 494) = 1

GCD of 18, 402, 191, 494 is 1
