Make use of GCD Calculator to determine the Greatest Common Divisor of 457, 458, 515, 789 i.e. 1 largest integer that divides all the numbers equally.
GCD of 457, 458, 515, 789 is 1
GCD(457, 458, 515, 789) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 457, 458, 515, 789 is 1
GCD(457, 458, 515, 789) = 1
Given Input numbers are 457, 458, 515, 789
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 263, 789
Greatest Common Divisior
We found the divisors of 457, 458, 515, 789 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 457, 458, 515, 789 is 1.
Therefore, GCD of numbers 457, 458, 515, 789 is 1
Given Input Data is 457, 458, 515, 789
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 457 is 457
Prime Factorization of 458 is 2 x 229
Prime Factorization of 515 is 5 x 103
Prime Factorization of 789 is 3 x 263
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(457, 458) = 209306
GCD(457, 458) = ( 457 x 458 ) / 209306
GCD(457, 458) = 209306 / 209306
GCD(457, 458) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 515
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
GCD(1, 515) = 515 / 515
GCD(1, 515) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 789
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
GCD(1, 789) = 789 / 789
GCD(1, 789) = 1
GCD of 457, 458, 515, 789 is 1
