We found the divisors of 841, 129, 836, 206 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 841, 129, 836, 206 is 1.

Therefore, GCD of numbers 841, 129, 836, 206 is 1

Given Input Data is 841, 129, 836, 206

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

Prime Factorization of 841 is 29 x 29

Prime Factorization of 129 is 3 x 43

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

Prime Factorization of 206 is 2 x 103

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(841, 129) = 108489

GCD(841, 129) = ( 841 x 129 ) / 108489

GCD(841, 129) = 108489 / 108489

GCD(841, 129) = 1

Step2:

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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 206

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

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

GCD(1, 206) = 206 / 206

GCD(1, 206) = 1

GCD of 841, 129, 836, 206 is 1
