1, 449
Greatest Common Divisior
We found the divisors of 602, 915, 420, 449 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 602, 915, 420, 449 is 1.
Therefore, GCD of numbers 602, 915, 420, 449 is 1
Given Input Data is 602, 915, 420, 449
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 602 is 2 x 7 x 43
Prime Factorization of 915 is 3 x 5 x 61
Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7
Prime Factorization of 449 is 449
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(602, 915) = 550830
GCD(602, 915) = ( 602 x 915 ) / 550830
GCD(602, 915) = 550830 / 550830
GCD(602, 915) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 420
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
GCD(1, 420) = 420 / 420
GCD(1, 420) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 449
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
GCD(1, 449) = 449 / 449
GCD(1, 449) = 1
GCD of 602, 915, 420, 449 is 1
