Therefore, GCD of numbers 255, 900, 19, 840 is 1

Given Input Data is 255, 900, 19, 840

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

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 900 is 2 x 2 x 3 x 3 x 5 x 5

Prime Factorization of 19 is 19

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

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(255, 900) = 15300

GCD(255, 900) = ( 255 x 900 ) / 15300

GCD(255, 900) = 229500 / 15300

GCD(255, 900) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 19

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

LCM(15, 19) = 285

GCD(15, 19) = ( 15 x 19 ) / 285

GCD(15, 19) = 285 / 285

GCD(15, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 840

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

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

GCD(1, 840) = 840 / 840

GCD(1, 840) = 1

GCD of 255, 900, 19, 840 is 1
