1, 13, 67, 871
Greatest Common Divisior
We found the divisors of 788, 631, 65, 871 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 788, 631, 65, 871 is 1.
Therefore, GCD of numbers 788, 631, 65, 871 is 1
Given Input Data is 788, 631, 65, 871
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 788 is 2 x 2 x 197
Prime Factorization of 631 is 631
Prime Factorization of 65 is 5 x 13
Prime Factorization of 871 is 13 x 67
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(788, 631) = 497228
GCD(788, 631) = ( 788 x 631 ) / 497228
GCD(788, 631) = 497228 / 497228
GCD(788, 631) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 65
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
GCD(1, 65) = 65 / 65
GCD(1, 65) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 871
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
GCD(1, 871) = 871 / 871
GCD(1, 871) = 1
GCD of 788, 631, 65, 871 is 1
