Greatest Common Divisior
We found the divisors of 428, 443, 81, 896 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 428, 443, 81, 896 is 1.
Therefore, GCD of numbers 428, 443, 81, 896 is 1
Given Input Data is 428, 443, 81, 896
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 428 is 2 x 2 x 107
Prime Factorization of 443 is 443
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 896 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 7
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(428, 443) = 189604
GCD(428, 443) = ( 428 x 443 ) / 189604
GCD(428, 443) = 189604 / 189604
GCD(428, 443) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
GCD(1, 81) = 81 / 81
GCD(1, 81) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 896
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 896) = 896
GCD(1, 896) = ( 1 x 896 ) / 896
GCD(1, 896) = 896 / 896
GCD(1, 896) = 1
GCD of 428, 443, 81, 896 is 1
