Greatest Common Divisior
We found the divisors of 78, 382, 657, 205 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 78, 382, 657, 205 is 1.
Therefore, GCD of numbers 78, 382, 657, 205 is 1
Given Input Data is 78, 382, 657, 205
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 382 is 2 x 191
Prime Factorization of 657 is 3 x 3 x 73
Prime Factorization of 205 is 5 x 41
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(78, 382) = 14898
GCD(78, 382) = ( 78 x 382 ) / 14898
GCD(78, 382) = 29796 / 14898
GCD(78, 382) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 657
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 657) = 1314
GCD(2, 657) = ( 2 x 657 ) / 1314
GCD(2, 657) = 1314 / 1314
GCD(2, 657) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 205
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
GCD(1, 205) = 205 / 205
GCD(1, 205) = 1
GCD of 78, 382, 657, 205 is 1
