Given Input Data is 205, 300, 55, 285

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

Prime Factorization of 205 is 5 x 41

Prime Factorization of 300 is 2 x 2 x 3 x 5 x 5

Prime Factorization of 55 is 5 x 11

Prime Factorization of 285 is 3 x 5 x 19

Highest common occurrences in the given inputs are 5¹

Multiplying them we get the GCD as 5

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(205, 300) = 12300

GCD(205, 300) = ( 205 x 300 ) / 12300

GCD(205, 300) = 61500 / 12300

GCD(205, 300) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 55

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

LCM(5, 55) = 55

GCD(5, 55) = ( 5 x 55 ) / 55

GCD(5, 55) = 275 / 55

GCD(5, 55) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 285

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

LCM(5, 285) = 285

GCD(5, 285) = ( 5 x 285 ) / 285

GCD(5, 285) = 1425 / 285

GCD(5, 285) = 5

GCD of 205, 300, 55, 285 is 5
