1, 5, 83, 415
Greatest Common Divisior
We found the divisors of 403, 715, 747, 415 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 403, 715, 747, 415 is 1.
Therefore, GCD of numbers 403, 715, 747, 415 is 1
Given Input Data is 403, 715, 747, 415
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 403 is 13 x 31
Prime Factorization of 715 is 5 x 11 x 13
Prime Factorization of 747 is 3 x 3 x 83
Prime Factorization of 415 is 5 x 83
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(403, 715) = 22165
GCD(403, 715) = ( 403 x 715 ) / 22165
GCD(403, 715) = 288145 / 22165
GCD(403, 715) = 13
Step2:
Here we consider the GCD from the above i.e. 13 as first number and the next as 747
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(13, 747) = 9711
GCD(13, 747) = ( 13 x 747 ) / 9711
GCD(13, 747) = 9711 / 9711
GCD(13, 747) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 415
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
GCD(1, 415) = 415 / 415
GCD(1, 415) = 1
GCD of 403, 715, 747, 415 is 1
