Given Input Data is 105, 810, 29, 765

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

Prime Factorization of 105 is 3 x 5 x 7

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

Prime Factorization of 29 is 29

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

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(105, 810) = 5670

GCD(105, 810) = ( 105 x 810 ) / 5670

GCD(105, 810) = 85050 / 5670

GCD(105, 810) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 29

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

LCM(15, 29) = 435

GCD(15, 29) = ( 15 x 29 ) / 435

GCD(15, 29) = 435 / 435

GCD(15, 29) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 765

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

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

GCD(1, 765) = 765 / 765

GCD(1, 765) = 1

GCD of 105, 810, 29, 765 is 1
