Greatest Common Divisior
We found the divisors of 409, 680, 69, 549 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 409, 680, 69, 549 is 1.
Therefore, GCD of numbers 409, 680, 69, 549 is 1
Given Input Data is 409, 680, 69, 549
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 409 is 409
Prime Factorization of 680 is 2 x 2 x 2 x 5 x 17
Prime Factorization of 69 is 3 x 23
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(409, 680) = 278120
GCD(409, 680) = ( 409 x 680 ) / 278120
GCD(409, 680) = 278120 / 278120
GCD(409, 680) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 69
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 69) = 69
GCD(1, 69) = ( 1 x 69 ) / 69
GCD(1, 69) = 69 / 69
GCD(1, 69) = 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 409, 680, 69, 549 is 1
