Greatest Common Divisior
We found the divisors of 620, 717, 945, 194 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 620, 717, 945, 194 is 1.
Therefore, GCD of numbers 620, 717, 945, 194 is 1
Given Input Data is 620, 717, 945, 194
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 620 is 2 x 2 x 5 x 31
Prime Factorization of 717 is 3 x 239
Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7
Prime Factorization of 194 is 2 x 97
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(620, 717) = 444540
GCD(620, 717) = ( 620 x 717 ) / 444540
GCD(620, 717) = 444540 / 444540
GCD(620, 717) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 945
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
GCD(1, 945) = 945 / 945
GCD(1, 945) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 194
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 194) = 194
GCD(1, 194) = ( 1 x 194 ) / 194
GCD(1, 194) = 194 / 194
GCD(1, 194) = 1
GCD of 620, 717, 945, 194 is 1
