Greatest Common Divisior
We found the divisors of 877, 392, 479, 638 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 877, 392, 479, 638 is 1.
Therefore, GCD of numbers 877, 392, 479, 638 is 1
Given Input Data is 877, 392, 479, 638
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 877 is 877
Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7
Prime Factorization of 479 is 479
Prime Factorization of 638 is 2 x 11 x 29
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(877, 392) = 343784
GCD(877, 392) = ( 877 x 392 ) / 343784
GCD(877, 392) = 343784 / 343784
GCD(877, 392) = 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 638
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
GCD(1, 638) = 638 / 638
GCD(1, 638) = 1
GCD of 877, 392, 479, 638 is 1
