Greatest Common Divisior
We found the divisors of 392, 641, 636, 863 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 392, 641, 636, 863 is 1.
Therefore, GCD of numbers 392, 641, 636, 863 is 1
Given Input Data is 392, 641, 636, 863
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7
Prime Factorization of 641 is 641
Prime Factorization of 636 is 2 x 2 x 3 x 53
Prime Factorization of 863 is 863
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(392, 641) = 251272
GCD(392, 641) = ( 392 x 641 ) / 251272
GCD(392, 641) = 251272 / 251272
GCD(392, 641) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 636
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 636) = 636
GCD(1, 636) = ( 1 x 636 ) / 636
GCD(1, 636) = 636 / 636
GCD(1, 636) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 863
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
GCD(1, 863) = 863 / 863
GCD(1, 863) = 1
GCD of 392, 641, 636, 863 is 1
