1, 3, 83, 249
Greatest Common Divisior
We found the divisors of 20, 681, 944, 249 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 20, 681, 944, 249 is 1.
Therefore, GCD of numbers 20, 681, 944, 249 is 1
Given Input Data is 20, 681, 944, 249
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 681 is 3 x 227
Prime Factorization of 944 is 2 x 2 x 2 x 2 x 59
Prime Factorization of 249 is 3 x 83
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(20, 681) = 13620
GCD(20, 681) = ( 20 x 681 ) / 13620
GCD(20, 681) = 13620 / 13620
GCD(20, 681) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 944
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 944) = 944
GCD(1, 944) = ( 1 x 944 ) / 944
GCD(1, 944) = 944 / 944
GCD(1, 944) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 249
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
GCD(1, 249) = 249 / 249
GCD(1, 249) = 1
GCD of 20, 681, 944, 249 is 1
