Make use of GCD Calculator to determine the Greatest Common Divisor of 243, 473, 256 i.e. 1 largest integer that divides all the numbers equally.
GCD of 243, 473, 256 is 1
GCD(243, 473, 256) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 243, 473, 256 is 1
GCD(243, 473, 256) = 1
Given Input numbers are 243, 473, 256
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 4, 8, 16, 32, 64, 128, 256
Greatest Common Divisior
We found the divisors of 243, 473, 256 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 243, 473, 256 is 1.
Therefore, GCD of numbers 243, 473, 256 is 1
Given Input Data is 243, 473, 256
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3
Prime Factorization of 473 is 11 x 43
Prime Factorization of 256 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2
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(243, 473) = 114939
GCD(243, 473) = ( 243 x 473 ) / 114939
GCD(243, 473) = 114939 / 114939
GCD(243, 473) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 256
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
GCD(1, 256) = 256 / 256
GCD(1, 256) = 1
GCD of 243, 473, 256 is 1
