Greatest Common Divisior
We found the divisors of 103, 406, 480, 291 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 103, 406, 480, 291 is 1.
Therefore, GCD of numbers 103, 406, 480, 291 is 1
Given Input Data is 103, 406, 480, 291
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 103 is 103
Prime Factorization of 406 is 2 x 7 x 29
Prime Factorization of 480 is 2 x 2 x 2 x 2 x 2 x 3 x 5
Prime Factorization of 291 is 3 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(103, 406) = 41818
GCD(103, 406) = ( 103 x 406 ) / 41818
GCD(103, 406) = 41818 / 41818
GCD(103, 406) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 480
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 480) = 480
GCD(1, 480) = ( 1 x 480 ) / 480
GCD(1, 480) = 480 / 480
GCD(1, 480) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 291
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
GCD(1, 291) = 291 / 291
GCD(1, 291) = 1
GCD of 103, 406, 480, 291 is 1
