We found the divisors of 821, 261, 826, 836 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 821, 261, 826, 836 is 1.

Therefore, GCD of numbers 821, 261, 826, 836 is 1

Given Input Data is 821, 261, 826, 836

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

Prime Factorization of 821 is 821

Prime Factorization of 261 is 3 x 3 x 29

Prime Factorization of 826 is 2 x 7 x 59

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(821, 261) = 214281

GCD(821, 261) = ( 821 x 261 ) / 214281

GCD(821, 261) = 214281 / 214281

GCD(821, 261) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 826

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

LCM(1, 826) = 826

GCD(1, 826) = ( 1 x 826 ) / 826

GCD(1, 826) = 826 / 826

GCD(1, 826) = 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 821, 261, 826, 836 is 1
