Greatest Common Divisior
We found the divisors of 291, 415, 961, 783 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 291, 415, 961, 783 is 1.
Therefore, GCD of numbers 291, 415, 961, 783 is 1
Given Input Data is 291, 415, 961, 783
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 291 is 3 x 97
Prime Factorization of 415 is 5 x 83
Prime Factorization of 961 is 31 x 31
Prime Factorization of 783 is 3 x 3 x 3 x 29
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(291, 415) = 120765
GCD(291, 415) = ( 291 x 415 ) / 120765
GCD(291, 415) = 120765 / 120765
GCD(291, 415) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 961
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 961) = 961
GCD(1, 961) = ( 1 x 961 ) / 961
GCD(1, 961) = 961 / 961
GCD(1, 961) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 783
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
GCD(1, 783) = 783 / 783
GCD(1, 783) = 1
GCD of 291, 415, 961, 783 is 1
