Greatest Common Divisior
We found the divisors of 657, 130, 793, 305 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 657, 130, 793, 305 is 1.
Therefore, GCD of numbers 657, 130, 793, 305 is 1
Given Input Data is 657, 130, 793, 305
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 657 is 3 x 3 x 73
Prime Factorization of 130 is 2 x 5 x 13
Prime Factorization of 793 is 13 x 61
Prime Factorization of 305 is 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(657, 130) = 85410
GCD(657, 130) = ( 657 x 130 ) / 85410
GCD(657, 130) = 85410 / 85410
GCD(657, 130) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 793
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 793) = 793
GCD(1, 793) = ( 1 x 793 ) / 793
GCD(1, 793) = 793 / 793
GCD(1, 793) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 305
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
GCD(1, 305) = 305 / 305
GCD(1, 305) = 1
GCD of 657, 130, 793, 305 is 1
