1, 3, 7, 21, 41, 123, 287, 861
Greatest Common Divisior
We found the divisors of 756, 365, 55, 861 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 756, 365, 55, 861 is 1.
Therefore, GCD of numbers 756, 365, 55, 861 is 1
Given Input Data is 756, 365, 55, 861
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 756 is 2 x 2 x 3 x 3 x 3 x 7
Prime Factorization of 365 is 5 x 73
Prime Factorization of 55 is 5 x 11
Prime Factorization of 861 is 3 x 7 x 41
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(756, 365) = 275940
GCD(756, 365) = ( 756 x 365 ) / 275940
GCD(756, 365) = 275940 / 275940
GCD(756, 365) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 55
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 55) = 55
GCD(1, 55) = ( 1 x 55 ) / 55
GCD(1, 55) = 55 / 55
GCD(1, 55) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 861
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
GCD(1, 861) = 861 / 861
GCD(1, 861) = 1
GCD of 756, 365, 55, 861 is 1
