1, 7, 107, 749
Greatest Common Divisior
We found the divisors of 756, 969, 790, 749 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 756, 969, 790, 749 is 1.
Therefore, GCD of numbers 756, 969, 790, 749 is 1
Given Input Data is 756, 969, 790, 749
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 969 is 3 x 17 x 19
Prime Factorization of 790 is 2 x 5 x 79
Prime Factorization of 749 is 7 x 107
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, 969) = 244188
GCD(756, 969) = ( 756 x 969 ) / 244188
GCD(756, 969) = 732564 / 244188
GCD(756, 969) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 790
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 790) = 2370
GCD(3, 790) = ( 3 x 790 ) / 2370
GCD(3, 790) = 2370 / 2370
GCD(3, 790) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 749
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 749) = 749
GCD(1, 749) = ( 1 x 749 ) / 749
GCD(1, 749) = 749 / 749
GCD(1, 749) = 1
GCD of 756, 969, 790, 749 is 1
