Greatest Common Divisior
We found the divisors of 959, 121, 505, 643 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 959, 121, 505, 643 is 1.
Therefore, GCD of numbers 959, 121, 505, 643 is 1
Given Input Data is 959, 121, 505, 643
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 959 is 7 x 137
Prime Factorization of 121 is 11 x 11
Prime Factorization of 505 is 5 x 101
Prime Factorization of 643 is 643
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(959, 121) = 116039
GCD(959, 121) = ( 959 x 121 ) / 116039
GCD(959, 121) = 116039 / 116039
GCD(959, 121) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 505
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 505) = 505
GCD(1, 505) = ( 1 x 505 ) / 505
GCD(1, 505) = 505 / 505
GCD(1, 505) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 643
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
GCD(1, 643) = 643 / 643
GCD(1, 643) = 1
GCD of 959, 121, 505, 643 is 1
