Therefore, GCD of numbers 195, 585, 49, 489 is 1

Given Input Data is 195, 585, 49, 489

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

Prime Factorization of 195 is 3 x 5 x 13

Prime Factorization of 585 is 3 x 3 x 5 x 13

Prime Factorization of 49 is 7 x 7

Prime Factorization of 489 is 3 x 163

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(195, 585) = 585

GCD(195, 585) = ( 195 x 585 ) / 585

GCD(195, 585) = 114075 / 585

GCD(195, 585) = 195

Step2:

Here we consider the GCD from the above i.e. 195 as first number and the next as 49

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

LCM(195, 49) = 9555

GCD(195, 49) = ( 195 x 49 ) / 9555

GCD(195, 49) = 9555 / 9555

GCD(195, 49) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 489

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

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

GCD(1, 489) = 489 / 489

GCD(1, 489) = 1

GCD of 195, 585, 49, 489 is 1
