Greatest Common Divisior
We found the divisors of 731, 189, 78, 171 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 731, 189, 78, 171 is 1.
Therefore, GCD of numbers 731, 189, 78, 171 is 1
Given Input Data is 731, 189, 78, 171
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 731 is 17 x 43
Prime Factorization of 189 is 3 x 3 x 3 x 7
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 171 is 3 x 3 x 19
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(731, 189) = 138159
GCD(731, 189) = ( 731 x 189 ) / 138159
GCD(731, 189) = 138159 / 138159
GCD(731, 189) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 78
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 78) = 78
GCD(1, 78) = ( 1 x 78 ) / 78
GCD(1, 78) = 78 / 78
GCD(1, 78) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 171
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 171) = 171
GCD(1, 171) = ( 1 x 171 ) / 171
GCD(1, 171) = 171 / 171
GCD(1, 171) = 1
GCD of 731, 189, 78, 171 is 1
