Greatest Common Divisior
We found the divisors of 378, 221, 439, 511 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 378, 221, 439, 511 is 1.
Therefore, GCD of numbers 378, 221, 439, 511 is 1
Given Input Data is 378, 221, 439, 511
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 221 is 13 x 17
Prime Factorization of 439 is 439
Prime Factorization of 511 is 7 x 73
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, 221) = 83538
GCD(378, 221) = ( 378 x 221 ) / 83538
GCD(378, 221) = 83538 / 83538
GCD(378, 221) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 439
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
GCD(1, 439) = 439 / 439
GCD(1, 439) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 511
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 511) = 511
GCD(1, 511) = ( 1 x 511 ) / 511
GCD(1, 511) = 511 / 511
GCD(1, 511) = 1
GCD of 378, 221, 439, 511 is 1
