Greatest Common Divisior
We found the divisors of 550, 558, 623, 443 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 550, 558, 623, 443 is 1.
Therefore, GCD of numbers 550, 558, 623, 443 is 1
Given Input Data is 550, 558, 623, 443
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 550 is 2 x 5 x 5 x 11
Prime Factorization of 558 is 2 x 3 x 3 x 31
Prime Factorization of 623 is 7 x 89
Prime Factorization of 443 is 443
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(550, 558) = 153450
GCD(550, 558) = ( 550 x 558 ) / 153450
GCD(550, 558) = 306900 / 153450
GCD(550, 558) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 623
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 623) = 1246
GCD(2, 623) = ( 2 x 623 ) / 1246
GCD(2, 623) = 1246 / 1246
GCD(2, 623) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 443
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
GCD(1, 443) = 443 / 443
GCD(1, 443) = 1
GCD of 550, 558, 623, 443 is 1
