Greatest Common Divisior
We found the divisors of 856, 903, 64, 561 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 856, 903, 64, 561 is 1.
Therefore, GCD of numbers 856, 903, 64, 561 is 1
Given Input Data is 856, 903, 64, 561
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 856 is 2 x 2 x 2 x 107
Prime Factorization of 903 is 3 x 7 x 43
Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 561 is 3 x 11 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(856, 903) = 772968
GCD(856, 903) = ( 856 x 903 ) / 772968
GCD(856, 903) = 772968 / 772968
GCD(856, 903) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 64
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
GCD(1, 64) = 64 / 64
GCD(1, 64) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 561
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
GCD(1, 561) = 561 / 561
GCD(1, 561) = 1
GCD of 856, 903, 64, 561 is 1
