Therefore, GCD of numbers 750, 669, 18, 812 is 1

Given Input Data is 750, 669, 18, 812

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

Prime Factorization of 750 is 2 x 3 x 5 x 5 x 5

Prime Factorization of 669 is 3 x 223

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 812 is 2 x 2 x 7 x 29

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(750, 669) = 167250

GCD(750, 669) = ( 750 x 669 ) / 167250

GCD(750, 669) = 501750 / 167250

GCD(750, 669) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 18

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

LCM(3, 18) = 18

GCD(3, 18) = ( 3 x 18 ) / 18

GCD(3, 18) = 54 / 18

GCD(3, 18) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 812

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

LCM(3, 812) = 2436

GCD(3, 812) = ( 3 x 812 ) / 2436

GCD(3, 812) = 2436 / 2436

GCD(3, 812) = 1

GCD of 750, 669, 18, 812 is 1
