Greatest Common Divisior
We found the divisors of 121, 286, 789, 246 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 121, 286, 789, 246 is 1.
Therefore, GCD of numbers 121, 286, 789, 246 is 1
Given Input Data is 121, 286, 789, 246
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 121 is 11 x 11
Prime Factorization of 286 is 2 x 11 x 13
Prime Factorization of 789 is 3 x 263
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(121, 286) = 3146
GCD(121, 286) = ( 121 x 286 ) / 3146
GCD(121, 286) = 34606 / 3146
GCD(121, 286) = 11
Step2:
Here we consider the GCD from the above i.e. 11 as first number and the next as 789
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(11, 789) = 8679
GCD(11, 789) = ( 11 x 789 ) / 8679
GCD(11, 789) = 8679 / 8679
GCD(11, 789) = 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 121, 286, 789, 246 is 1
