1, 691
Greatest Common Divisior
We found the divisors of 186, 387, 29, 691 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 186, 387, 29, 691 is 1.
Therefore, GCD of numbers 186, 387, 29, 691 is 1
Given Input Data is 186, 387, 29, 691
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 186 is 2 x 3 x 31
Prime Factorization of 387 is 3 x 3 x 43
Prime Factorization of 29 is 29
Prime Factorization of 691 is 691
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(186, 387) = 23994
GCD(186, 387) = ( 186 x 387 ) / 23994
GCD(186, 387) = 71982 / 23994
GCD(186, 387) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 29
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 29) = 87
GCD(3, 29) = ( 3 x 29 ) / 87
GCD(3, 29) = 87 / 87
GCD(3, 29) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 691
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
GCD(1, 691) = 691 / 691
GCD(1, 691) = 1
GCD of 186, 387, 29, 691 is 1
