Greatest Common Divisior
We found the divisors of 457, 855, 663, 680 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 457, 855, 663, 680 is 1.
Therefore, GCD of numbers 457, 855, 663, 680 is 1
Given Input Data is 457, 855, 663, 680
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 457 is 457
Prime Factorization of 855 is 3 x 3 x 5 x 19
Prime Factorization of 663 is 3 x 13 x 17
Prime Factorization of 680 is 2 x 2 x 2 x 5 x 17
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(457, 855) = 390735
GCD(457, 855) = ( 457 x 855 ) / 390735
GCD(457, 855) = 390735 / 390735
GCD(457, 855) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 663
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
GCD(1, 663) = 663 / 663
GCD(1, 663) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 680
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
GCD(1, 680) = 680 / 680
GCD(1, 680) = 1
GCD of 457, 855, 663, 680 is 1
