Greatest Common Divisior
We found the divisors of 409, 445, 207, 128 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 409, 445, 207, 128 is 1.
Therefore, GCD of numbers 409, 445, 207, 128 is 1
Given Input Data is 409, 445, 207, 128
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 409 is 409
Prime Factorization of 445 is 5 x 89
Prime Factorization of 207 is 3 x 3 x 23
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
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(409, 445) = 182005
GCD(409, 445) = ( 409 x 445 ) / 182005
GCD(409, 445) = 182005 / 182005
GCD(409, 445) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 207
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
GCD(1, 207) = 207 / 207
GCD(1, 207) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 128
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
GCD(1, 128) = 128 / 128
GCD(1, 128) = 1
GCD of 409, 445, 207, 128 is 1
