Given Input Data is 780, 255, 219, 927

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

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 219 is 3 x 73

Prime Factorization of 927 is 3 x 3 x 103

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

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(780, 255) = 13260

GCD(780, 255) = ( 780 x 255 ) / 13260

GCD(780, 255) = 198900 / 13260

GCD(780, 255) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 219

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

LCM(15, 219) = 1095

GCD(15, 219) = ( 15 x 219 ) / 1095

GCD(15, 219) = 3285 / 1095

GCD(15, 219) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 927

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

LCM(3, 927) = 927

GCD(3, 927) = ( 3 x 927 ) / 927

GCD(3, 927) = 2781 / 927

GCD(3, 927) = 3

GCD of 780, 255, 219, 927 is 3
