Greatest Common Divisior
We found the divisors of 517, 327, 790, 639 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 517, 327, 790, 639 is 1.
Therefore, GCD of numbers 517, 327, 790, 639 is 1
Given Input Data is 517, 327, 790, 639
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 517 is 11 x 47
Prime Factorization of 327 is 3 x 109
Prime Factorization of 790 is 2 x 5 x 79
Prime Factorization of 639 is 3 x 3 x 71
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(517, 327) = 169059
GCD(517, 327) = ( 517 x 327 ) / 169059
GCD(517, 327) = 169059 / 169059
GCD(517, 327) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 790
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
GCD(1, 790) = 790 / 790
GCD(1, 790) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 639
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
GCD(1, 639) = 639 / 639
GCD(1, 639) = 1
GCD of 517, 327, 790, 639 is 1
