Greatest Common Divisior
We found the divisors of 218, 388, 430, 178 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 218, 388, 430, 178 is 2.
Therefore, GCD of numbers 218, 388, 430, 178 is 2
Given Input Data is 218, 388, 430, 178
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 218 is 2 x 109
Prime Factorization of 388 is 2 x 2 x 97
Prime Factorization of 430 is 2 x 5 x 43
Prime Factorization of 178 is 2 x 89
Highest common occurrences in the given inputs are 21
Multiplying them we get the GCD as 2
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(218, 388) = 42292
GCD(218, 388) = ( 218 x 388 ) / 42292
GCD(218, 388) = 84584 / 42292
GCD(218, 388) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 430
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 430) = 430
GCD(2, 430) = ( 2 x 430 ) / 430
GCD(2, 430) = 860 / 430
GCD(2, 430) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 178
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 178) = 178
GCD(2, 178) = ( 2 x 178 ) / 178
GCD(2, 178) = 356 / 178
GCD(2, 178) = 2
GCD of 218, 388, 430, 178 is 2
