Greatest Common Divisior
We found the divisors of 280, 615, 444, 873 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 280, 615, 444, 873 is 1.
Therefore, GCD of numbers 280, 615, 444, 873 is 1
Given Input Data is 280, 615, 444, 873
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7
Prime Factorization of 615 is 3 x 5 x 41
Prime Factorization of 444 is 2 x 2 x 3 x 37
Prime Factorization of 873 is 3 x 3 x 97
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(280, 615) = 34440
GCD(280, 615) = ( 280 x 615 ) / 34440
GCD(280, 615) = 172200 / 34440
GCD(280, 615) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 444
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 444) = 2220
GCD(5, 444) = ( 5 x 444 ) / 2220
GCD(5, 444) = 2220 / 2220
GCD(5, 444) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 873
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 873) = 873
GCD(1, 873) = ( 1 x 873 ) / 873
GCD(1, 873) = 873 / 873
GCD(1, 873) = 1
GCD of 280, 615, 444, 873 is 1
