Greatest Common Divisior
We found the divisors of 899, 156, 15, 720 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 899, 156, 15, 720 is 1.
Therefore, GCD of numbers 899, 156, 15, 720 is 1
Given Input Data is 899, 156, 15, 720
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 899 is 29 x 31
Prime Factorization of 156 is 2 x 2 x 3 x 13
Prime Factorization of 15 is 3 x 5
Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5
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(899, 156) = 140244
GCD(899, 156) = ( 899 x 156 ) / 140244
GCD(899, 156) = 140244 / 140244
GCD(899, 156) = 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 720
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
GCD(1, 720) = 720 / 720
GCD(1, 720) = 1
GCD of 899, 156, 15, 720 is 1
