1, 17, 47, 799
Greatest Common Divisior
We found the divisors of 822, 420, 799 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 822, 420, 799 is 1.
Therefore, GCD of numbers 822, 420, 799 is 1
Given Input Data is 822, 420, 799
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 822 is 2 x 3 x 137
Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7
Prime Factorization of 799 is 17 x 47
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(822, 420) = 57540
GCD(822, 420) = ( 822 x 420 ) / 57540
GCD(822, 420) = 345240 / 57540
GCD(822, 420) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 799
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 799) = 4794
GCD(6, 799) = ( 6 x 799 ) / 4794
GCD(6, 799) = 4794 / 4794
GCD(6, 799) = 1
GCD of 822, 420, 799 is 1
