Greatest Common Divisior
We found the divisors of 785, 258, 84, 915 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 785, 258, 84, 915 is 1.
Therefore, GCD of numbers 785, 258, 84, 915 is 1
Given Input Data is 785, 258, 84, 915
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 785 is 5 x 157
Prime Factorization of 258 is 2 x 3 x 43
Prime Factorization of 84 is 2 x 2 x 3 x 7
Prime Factorization of 915 is 3 x 5 x 61
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(785, 258) = 202530
GCD(785, 258) = ( 785 x 258 ) / 202530
GCD(785, 258) = 202530 / 202530
GCD(785, 258) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 84
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 84) = 84
GCD(1, 84) = ( 1 x 84 ) / 84
GCD(1, 84) = 84 / 84
GCD(1, 84) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 915
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
GCD(1, 915) = 915 / 915
GCD(1, 915) = 1
GCD of 785, 258, 84, 915 is 1
