Greatest Common Divisior
We found the divisors of 378, 621, 520, 605 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 378, 621, 520, 605 is 1.
Therefore, GCD of numbers 378, 621, 520, 605 is 1
Given Input Data is 378, 621, 520, 605
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 378 is 2 x 3 x 3 x 3 x 7
Prime Factorization of 621 is 3 x 3 x 3 x 23
Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13
Prime Factorization of 605 is 5 x 11 x 11
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(378, 621) = 8694
GCD(378, 621) = ( 378 x 621 ) / 8694
GCD(378, 621) = 234738 / 8694
GCD(378, 621) = 27
Step2:
Here we consider the GCD from the above i.e. 27 as first number and the next as 520
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(27, 520) = 14040
GCD(27, 520) = ( 27 x 520 ) / 14040
GCD(27, 520) = 14040 / 14040
GCD(27, 520) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 605
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
GCD(1, 605) = 605 / 605
GCD(1, 605) = 1
GCD of 378, 621, 520, 605 is 1
