Given Input Data is 810, 555, 627, 765

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

Prime Factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 627 is 3 x 11 x 19

Prime Factorization of 765 is 3 x 3 x 5 x 17

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(810, 555) = 29970

GCD(810, 555) = ( 810 x 555 ) / 29970

GCD(810, 555) = 449550 / 29970

GCD(810, 555) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 627

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

LCM(15, 627) = 3135

GCD(15, 627) = ( 15 x 627 ) / 3135

GCD(15, 627) = 9405 / 3135

GCD(15, 627) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 765

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

LCM(3, 765) = 765

GCD(3, 765) = ( 3 x 765 ) / 765

GCD(3, 765) = 2295 / 765

GCD(3, 765) = 3

GCD of 810, 555, 627, 765 is 3
