Greatest Common Divisior
We found the divisors of 287, 676, 392, 549 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 287, 676, 392, 549 is 1.
Therefore, GCD of numbers 287, 676, 392, 549 is 1
Given Input Data is 287, 676, 392, 549
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 287 is 7 x 41
Prime Factorization of 676 is 2 x 2 x 13 x 13
Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7
Prime Factorization of 549 is 3 x 3 x 61
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(287, 676) = 194012
GCD(287, 676) = ( 287 x 676 ) / 194012
GCD(287, 676) = 194012 / 194012
GCD(287, 676) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 392
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
GCD(1, 392) = 392 / 392
GCD(1, 392) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 549
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
GCD(1, 549) = 549 / 549
GCD(1, 549) = 1
GCD of 287, 676, 392, 549 is 1
