1, 7, 103, 721
Greatest Common Divisior
We found the divisors of 209, 671, 534, 721 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 209, 671, 534, 721 is 1.
Therefore, GCD of numbers 209, 671, 534, 721 is 1
Given Input Data is 209, 671, 534, 721
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 209 is 11 x 19
Prime Factorization of 671 is 11 x 61
Prime Factorization of 534 is 2 x 3 x 89
Prime Factorization of 721 is 7 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(209, 671) = 12749
GCD(209, 671) = ( 209 x 671 ) / 12749
GCD(209, 671) = 140239 / 12749
GCD(209, 671) = 11
Step2:
Here we consider the GCD from the above i.e. 11 as first number and the next as 534
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(11, 534) = 5874
GCD(11, 534) = ( 11 x 534 ) / 5874
GCD(11, 534) = 5874 / 5874
GCD(11, 534) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 721
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
GCD(1, 721) = 721 / 721
GCD(1, 721) = 1
GCD of 209, 671, 534, 721 is 1
