Greatest Common Divisior
We found the divisors of 568, 549, 43, 639 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 568, 549, 43, 639 is 1.
Therefore, GCD of numbers 568, 549, 43, 639 is 1
Given Input Data is 568, 549, 43, 639
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 568 is 2 x 2 x 2 x 71
Prime Factorization of 549 is 3 x 3 x 61
Prime Factorization of 43 is 43
Prime Factorization of 639 is 3 x 3 x 71
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(568, 549) = 311832
GCD(568, 549) = ( 568 x 549 ) / 311832
GCD(568, 549) = 311832 / 311832
GCD(568, 549) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 43
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 43) = 43
GCD(1, 43) = ( 1 x 43 ) / 43
GCD(1, 43) = 43 / 43
GCD(1, 43) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 639
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
GCD(1, 639) = 639 / 639
GCD(1, 639) = 1
GCD of 568, 549, 43, 639 is 1
