Greatest Common Divisior
We found the divisors of 285, 521, 205, 891 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 285, 521, 205, 891 is 1.
Therefore, GCD of numbers 285, 521, 205, 891 is 1
Given Input Data is 285, 521, 205, 891
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 285 is 3 x 5 x 19
Prime Factorization of 521 is 521
Prime Factorization of 205 is 5 x 41
Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11
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(285, 521) = 148485
GCD(285, 521) = ( 285 x 521 ) / 148485
GCD(285, 521) = 148485 / 148485
GCD(285, 521) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 205
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
GCD(1, 205) = 205 / 205
GCD(1, 205) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 891
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
GCD(1, 891) = 891 / 891
GCD(1, 891) = 1
GCD of 285, 521, 205, 891 is 1
