Greatest Common Divisior
We found the divisors of 553, 515, 243 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 553, 515, 243 is 1.
Therefore, GCD of numbers 553, 515, 243 is 1
Given Input Data is 553, 515, 243
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 553 is 7 x 79
Prime Factorization of 515 is 5 x 103
Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3
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(553, 515) = 284795
GCD(553, 515) = ( 553 x 515 ) / 284795
GCD(553, 515) = 284795 / 284795
GCD(553, 515) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 243
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
GCD(1, 243) = 243 / 243
GCD(1, 243) = 1
GCD of 553, 515, 243 is 1
