Greatest Common Divisior
We found the divisors of 985, 457, 438, 395 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 985, 457, 438, 395 is 1.
Therefore, GCD of numbers 985, 457, 438, 395 is 1
Given Input Data is 985, 457, 438, 395
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 985 is 5 x 197
Prime Factorization of 457 is 457
Prime Factorization of 438 is 2 x 3 x 73
Prime Factorization of 395 is 5 x 79
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(985, 457) = 450145
GCD(985, 457) = ( 985 x 457 ) / 450145
GCD(985, 457) = 450145 / 450145
GCD(985, 457) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 438
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
GCD(1, 438) = 438 / 438
GCD(1, 438) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 395
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 395) = 395
GCD(1, 395) = ( 1 x 395 ) / 395
GCD(1, 395) = 395 / 395
GCD(1, 395) = 1
GCD of 985, 457, 438, 395 is 1
