Greatest Common Divisior
We found the divisors of 71, 639, 178, 386 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 71, 639, 178, 386 is 1.
Therefore, GCD of numbers 71, 639, 178, 386 is 1
Given Input Data is 71, 639, 178, 386
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 71 is 71
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 178 is 2 x 89
Prime Factorization of 386 is 2 x 193
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(71, 639) = 639
GCD(71, 639) = ( 71 x 639 ) / 639
GCD(71, 639) = 45369 / 639
GCD(71, 639) = 71
Step2:
Here we consider the GCD from the above i.e. 71 as first number and the next as 178
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(71, 178) = 12638
GCD(71, 178) = ( 71 x 178 ) / 12638
GCD(71, 178) = 12638 / 12638
GCD(71, 178) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 386
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 386) = 386
GCD(1, 386) = ( 1 x 386 ) / 386
GCD(1, 386) = 386 / 386
GCD(1, 386) = 1
GCD of 71, 639, 178, 386 is 1
