Greatest Common Divisior
We found the divisors of 777, 221, 418, 159 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 777, 221, 418, 159 is 1.
Therefore, GCD of numbers 777, 221, 418, 159 is 1
Given Input Data is 777, 221, 418, 159
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 777 is 3 x 7 x 37
Prime Factorization of 221 is 13 x 17
Prime Factorization of 418 is 2 x 11 x 19
Prime Factorization of 159 is 3 x 53
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(777, 221) = 171717
GCD(777, 221) = ( 777 x 221 ) / 171717
GCD(777, 221) = 171717 / 171717
GCD(777, 221) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 418
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 418) = 418
GCD(1, 418) = ( 1 x 418 ) / 418
GCD(1, 418) = 418 / 418
GCD(1, 418) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 159
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
GCD(1, 159) = 159 / 159
GCD(1, 159) = 1
GCD of 777, 221, 418, 159 is 1
