Given Input Data is 550, 285, 13, 528

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

Prime Factorization of 550 is 2 x 5 x 5 x 11

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 13 is 13

Prime Factorization of 528 is 2 x 2 x 2 x 2 x 3 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(550, 285) = 31350

GCD(550, 285) = ( 550 x 285 ) / 31350

GCD(550, 285) = 156750 / 31350

GCD(550, 285) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 13

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

LCM(5, 13) = 65

GCD(5, 13) = ( 5 x 13 ) / 65

GCD(5, 13) = 65 / 65

GCD(5, 13) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 528

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

LCM(1, 528) = 528

GCD(1, 528) = ( 1 x 528 ) / 528

GCD(1, 528) = 528 / 528

GCD(1, 528) = 1

GCD of 550, 285, 13, 528 is 1
