Greatest Common Divisior
We found the divisors of 409, 542, 785 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 409, 542, 785 is 1.
Therefore, GCD of numbers 409, 542, 785 is 1
Given Input Data is 409, 542, 785
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 409 is 409
Prime Factorization of 542 is 2 x 271
Prime Factorization of 785 is 5 x 157
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, 542) = 221678
GCD(409, 542) = ( 409 x 542 ) / 221678
GCD(409, 542) = 221678 / 221678
GCD(409, 542) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 785
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
GCD(1, 785) = 785 / 785
GCD(1, 785) = 1
GCD of 409, 542, 785 is 1
