1, 983
Greatest Common Divisior
We found the divisors of 855, 436, 81, 983 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 855, 436, 81, 983 is 1.
Therefore, GCD of numbers 855, 436, 81, 983 is 1
Given Input Data is 855, 436, 81, 983
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 855 is 3 x 3 x 5 x 19
Prime Factorization of 436 is 2 x 2 x 109
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 983 is 983
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(855, 436) = 372780
GCD(855, 436) = ( 855 x 436 ) / 372780
GCD(855, 436) = 372780 / 372780
GCD(855, 436) = 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 983
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 983) = 983
GCD(1, 983) = ( 1 x 983 ) / 983
GCD(1, 983) = 983 / 983
GCD(1, 983) = 1
GCD of 855, 436, 81, 983 is 1
