Therefore, GCD of numbers 285, 684, 48, 605 is 1

Given Input Data is 285, 684, 48, 605

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 684 is 2 x 2 x 3 x 3 x 19

Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3

Prime Factorization of 605 is 5 x 11 x 11

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, 684) = 3420

GCD(285, 684) = ( 285 x 684 ) / 3420

GCD(285, 684) = 194940 / 3420

GCD(285, 684) = 57

Step2:

Here we consider the GCD from the above i.e. 57 as first number and the next as 48

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

LCM(57, 48) = 912

GCD(57, 48) = ( 57 x 48 ) / 912

GCD(57, 48) = 2736 / 912

GCD(57, 48) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 605

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

LCM(3, 605) = 1815

GCD(3, 605) = ( 3 x 605 ) / 1815

GCD(3, 605) = 1815 / 1815

GCD(3, 605) = 1

GCD of 285, 684, 48, 605 is 1
