Greatest Common Divisior
We found the divisors of 280, 247, 555, 111 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 280, 247, 555, 111 is 1.
Therefore, GCD of numbers 280, 247, 555, 111 is 1
Given Input Data is 280, 247, 555, 111
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 247 is 13 x 19
Prime Factorization of 555 is 3 x 5 x 37
Prime Factorization of 111 is 3 x 37
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, 247) = 69160
GCD(280, 247) = ( 280 x 247 ) / 69160
GCD(280, 247) = 69160 / 69160
GCD(280, 247) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 555
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
GCD(1, 555) = 555 / 555
GCD(1, 555) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 111
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 111) = 111
GCD(1, 111) = ( 1 x 111 ) / 111
GCD(1, 111) = 111 / 111
GCD(1, 111) = 1
GCD of 280, 247, 555, 111 is 1
