Greatest Common Divisior
We found the divisors of 81, 286, 479, 840 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 81, 286, 479, 840 is 1.
Therefore, GCD of numbers 81, 286, 479, 840 is 1
Given Input Data is 81, 286, 479, 840
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 286 is 2 x 11 x 13
Prime Factorization of 479 is 479
Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7
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(81, 286) = 23166
GCD(81, 286) = ( 81 x 286 ) / 23166
GCD(81, 286) = 23166 / 23166
GCD(81, 286) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 479
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 479) = 479
GCD(1, 479) = ( 1 x 479 ) / 479
GCD(1, 479) = 479 / 479
GCD(1, 479) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 840
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
GCD(1, 840) = 840 / 840
GCD(1, 840) = 1
GCD of 81, 286, 479, 840 is 1
