Greatest Common Divisior
We found the divisors of 641, 605, 678, 557 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 641, 605, 678, 557 is 1.
Therefore, GCD of numbers 641, 605, 678, 557 is 1
Given Input Data is 641, 605, 678, 557
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 641 is 641
Prime Factorization of 605 is 5 x 11 x 11
Prime Factorization of 678 is 2 x 3 x 113
Prime Factorization of 557 is 557
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(641, 605) = 387805
GCD(641, 605) = ( 641 x 605 ) / 387805
GCD(641, 605) = 387805 / 387805
GCD(641, 605) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 678
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
GCD(1, 678) = 678 / 678
GCD(1, 678) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 557
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
GCD(1, 557) = 557 / 557
GCD(1, 557) = 1
GCD of 641, 605, 678, 557 is 1
