1, 809
Greatest Common Divisior
We found the divisors of 172, 399, 94, 809 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 172, 399, 94, 809 is 1.
Therefore, GCD of numbers 172, 399, 94, 809 is 1
Given Input Data is 172, 399, 94, 809
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 172 is 2 x 2 x 43
Prime Factorization of 399 is 3 x 7 x 19
Prime Factorization of 94 is 2 x 47
Prime Factorization of 809 is 809
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(172, 399) = 68628
GCD(172, 399) = ( 172 x 399 ) / 68628
GCD(172, 399) = 68628 / 68628
GCD(172, 399) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 94
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 94) = 94
GCD(1, 94) = ( 1 x 94 ) / 94
GCD(1, 94) = 94 / 94
GCD(1, 94) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 809
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
GCD(1, 809) = 809 / 809
GCD(1, 809) = 1
GCD of 172, 399, 94, 809 is 1
