Greatest Common Divisior
We found the divisors of 445, 720, 19, 246 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 445, 720, 19, 246 is 1.
Therefore, GCD of numbers 445, 720, 19, 246 is 1
Given Input Data is 445, 720, 19, 246
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 445 is 5 x 89
Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime Factorization of 19 is 19
Prime Factorization of 246 is 2 x 3 x 41
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(445, 720) = 64080
GCD(445, 720) = ( 445 x 720 ) / 64080
GCD(445, 720) = 320400 / 64080
GCD(445, 720) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 19
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 19) = 95
GCD(5, 19) = ( 5 x 19 ) / 95
GCD(5, 19) = 95 / 95
GCD(5, 19) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 246
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 246) = 246
GCD(1, 246) = ( 1 x 246 ) / 246
GCD(1, 246) = 246 / 246
GCD(1, 246) = 1
GCD of 445, 720, 19, 246 is 1
