1, 127
Greatest Common Divisior
We found the divisors of 405, 915, 503, 127 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 405, 915, 503, 127 is 1.
Therefore, GCD of numbers 405, 915, 503, 127 is 1
Given Input Data is 405, 915, 503, 127
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5
Prime Factorization of 915 is 3 x 5 x 61
Prime Factorization of 503 is 503
Prime Factorization of 127 is 127
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(405, 915) = 24705
GCD(405, 915) = ( 405 x 915 ) / 24705
GCD(405, 915) = 370575 / 24705
GCD(405, 915) = 15
Step2:
Here we consider the GCD from the above i.e. 15 as first number and the next as 503
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(15, 503) = 7545
GCD(15, 503) = ( 15 x 503 ) / 7545
GCD(15, 503) = 7545 / 7545
GCD(15, 503) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 127
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 127) = 127
GCD(1, 127) = ( 1 x 127 ) / 127
GCD(1, 127) = 127 / 127
GCD(1, 127) = 1
GCD of 405, 915, 503, 127 is 1
