Therefore, GCD of numbers 773, 714, 21, 836 is 1

Given Input Data is 773, 714, 21, 836

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

Prime Factorization of 773 is 773

Prime Factorization of 714 is 2 x 3 x 7 x 17

Prime Factorization of 21 is 3 x 7

Prime Factorization of 836 is 2 x 2 x 11 x 19

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(773, 714) = 551922

GCD(773, 714) = ( 773 x 714 ) / 551922

GCD(773, 714) = 551922 / 551922

GCD(773, 714) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

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

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 836

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

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

GCD(1, 836) = 836 / 836

GCD(1, 836) = 1

GCD of 773, 714, 21, 836 is 1
