Greatest Common Divisior
We found the divisors of 629, 743, 665, 561 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 629, 743, 665, 561 is 1.
Therefore, GCD of numbers 629, 743, 665, 561 is 1
Given Input Data is 629, 743, 665, 561
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 629 is 17 x 37
Prime Factorization of 743 is 743
Prime Factorization of 665 is 5 x 7 x 19
Prime Factorization of 561 is 3 x 11 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(629, 743) = 467347
GCD(629, 743) = ( 629 x 743 ) / 467347
GCD(629, 743) = 467347 / 467347
GCD(629, 743) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 665
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
GCD(1, 665) = 665 / 665
GCD(1, 665) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 561
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
GCD(1, 561) = 561 / 561
GCD(1, 561) = 1
GCD of 629, 743, 665, 561 is 1
