Greatest Common Divisior
We found the divisors of 387, 122, 641, 769 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 387, 122, 641, 769 is 1.
Therefore, GCD of numbers 387, 122, 641, 769 is 1
Given Input Data is 387, 122, 641, 769
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 387 is 3 x 3 x 43
Prime Factorization of 122 is 2 x 61
Prime Factorization of 641 is 641
Prime Factorization of 769 is 769
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(387, 122) = 47214
GCD(387, 122) = ( 387 x 122 ) / 47214
GCD(387, 122) = 47214 / 47214
GCD(387, 122) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 641
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
GCD(1, 641) = 641 / 641
GCD(1, 641) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 769
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 769) = 769
GCD(1, 769) = ( 1 x 769 ) / 769
GCD(1, 769) = 769 / 769
GCD(1, 769) = 1
GCD of 387, 122, 641, 769 is 1
