Therefore, GCD of numbers 407, 187, 83, 287 is 1

Given Input Data is 407, 187, 83, 287

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

Prime Factorization of 407 is 11 x 37

Prime Factorization of 187 is 11 x 17

Prime Factorization of 83 is 83

Prime Factorization of 287 is 7 x 41

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(407, 187) = 6919

GCD(407, 187) = ( 407 x 187 ) / 6919

GCD(407, 187) = 76109 / 6919

GCD(407, 187) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 83

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

LCM(11, 83) = 913

GCD(11, 83) = ( 11 x 83 ) / 913

GCD(11, 83) = 913 / 913

GCD(11, 83) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 287

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

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

GCD(1, 287) = 287 / 287

GCD(1, 287) = 1

GCD of 407, 187, 83, 287 is 1
