Greatest Common Divisior
We found the divisors of 649, 619, 15, 873 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 649, 619, 15, 873 is 1.
Therefore, GCD of numbers 649, 619, 15, 873 is 1
Given Input Data is 649, 619, 15, 873
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 649 is 11 x 59
Prime Factorization of 619 is 619
Prime Factorization of 15 is 3 x 5
Prime Factorization of 873 is 3 x 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(649, 619) = 401731
GCD(649, 619) = ( 649 x 619 ) / 401731
GCD(649, 619) = 401731 / 401731
GCD(649, 619) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 15
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
GCD(1, 15) = 15 / 15
GCD(1, 15) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 873
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 873) = 873
GCD(1, 873) = ( 1 x 873 ) / 873
GCD(1, 873) = 873 / 873
GCD(1, 873) = 1
GCD of 649, 619, 15, 873 is 1
