1, 3, 197, 591
Greatest Common Divisior
We found the divisors of 861, 888, 440, 591 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 861, 888, 440, 591 is 1.
Therefore, GCD of numbers 861, 888, 440, 591 is 1
Given Input Data is 861, 888, 440, 591
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 861 is 3 x 7 x 41
Prime Factorization of 888 is 2 x 2 x 2 x 3 x 37
Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11
Prime Factorization of 591 is 3 x 197
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(861, 888) = 254856
GCD(861, 888) = ( 861 x 888 ) / 254856
GCD(861, 888) = 764568 / 254856
GCD(861, 888) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 440
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 440) = 1320
GCD(3, 440) = ( 3 x 440 ) / 1320
GCD(3, 440) = 1320 / 1320
GCD(3, 440) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 591
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 591) = 591
GCD(1, 591) = ( 1 x 591 ) / 591
GCD(1, 591) = 591 / 591
GCD(1, 591) = 1
GCD of 861, 888, 440, 591 is 1
