Therefore, GCD of numbers 285, 310, 86, 903 is 1

Given Input Data is 285, 310, 86, 903

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

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 310 is 2 x 5 x 31

Prime Factorization of 86 is 2 x 43

Prime Factorization of 903 is 3 x 7 x 43

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(285, 310) = 17670

GCD(285, 310) = ( 285 x 310 ) / 17670

GCD(285, 310) = 88350 / 17670

GCD(285, 310) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 86

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

LCM(5, 86) = 430

GCD(5, 86) = ( 5 x 86 ) / 430

GCD(5, 86) = 430 / 430

GCD(5, 86) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 903

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

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

GCD(1, 903) = 903 / 903

GCD(1, 903) = 1

GCD of 285, 310, 86, 903 is 1
