Therefore, GCD of numbers 811, 823, 57, 765 is 1

Given Input Data is 811, 823, 57, 765

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

Prime Factorization of 811 is 811

Prime Factorization of 823 is 823

Prime Factorization of 57 is 3 x 19

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(811, 823) = 667453

GCD(811, 823) = ( 811 x 823 ) / 667453

GCD(811, 823) = 667453 / 667453

GCD(811, 823) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 57

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

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

GCD(1, 57) = 57 / 57

GCD(1, 57) = 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 811, 823, 57, 765 is 1
