Make use of GCD Calculator to determine the Greatest Common Divisor of 430, 215, 123 i.e. 1 largest integer that divides all the numbers equally.
GCD of 430, 215, 123 is 1
GCD(430, 215, 123) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 430, 215, 123 is 1
GCD(430, 215, 123) = 1
Given Input numbers are 430, 215, 123
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 430, 215, 123 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 430, 215, 123 is 1.
Therefore, GCD of numbers 430, 215, 123 is 1
Given Input Data is 430, 215, 123
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 430 is 2 x 5 x 43
Prime Factorization of 215 is 5 x 43
Prime Factorization of 123 is 3 x 41
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(430, 215) = 430
GCD(430, 215) = ( 430 x 215 ) / 430
GCD(430, 215) = 92450 / 430
GCD(430, 215) = 215
Step2:
Here we consider the GCD from the above i.e. 215 as first number and the next as 123
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(215, 123) = 26445
GCD(215, 123) = ( 215 x 123 ) / 26445
GCD(215, 123) = 26445 / 26445
GCD(215, 123) = 1
GCD of 430, 215, 123 is 1
