1, 3, 9, 11, 27, 33, 81, 99, 297, 891
Greatest Common Divisior
We found the divisors of 515, 143, 620, 891 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 515, 143, 620, 891 is 1.
Therefore, GCD of numbers 515, 143, 620, 891 is 1
Given Input Data is 515, 143, 620, 891
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 515 is 5 x 103
Prime Factorization of 143 is 11 x 13
Prime Factorization of 620 is 2 x 2 x 5 x 31
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(515, 143) = 73645
GCD(515, 143) = ( 515 x 143 ) / 73645
GCD(515, 143) = 73645 / 73645
GCD(515, 143) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 620
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
GCD(1, 620) = 620 / 620
GCD(1, 620) = 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 515, 143, 620, 891 is 1
