Make use of GCD Calculator to determine the Greatest Common Divisor of 405, 431, 86, 422 i.e. 1 largest integer that divides all the numbers equally.
GCD of 405, 431, 86, 422 is 1
GCD(405, 431, 86, 422) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 405, 431, 86, 422 is 1
GCD(405, 431, 86, 422) = 1
Given Input numbers are 405, 431, 86, 422
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 211, 422
Greatest Common Divisior
We found the divisors of 405, 431, 86, 422 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 405, 431, 86, 422 is 1.
Therefore, GCD of numbers 405, 431, 86, 422 is 1
Given Input Data is 405, 431, 86, 422
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5
Prime Factorization of 431 is 431
Prime Factorization of 86 is 2 x 43
Prime Factorization of 422 is 2 x 211
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(405, 431) = 174555
GCD(405, 431) = ( 405 x 431 ) / 174555
GCD(405, 431) = 174555 / 174555
GCD(405, 431) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 86
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 86) = 86
GCD(1, 86) = ( 1 x 86 ) / 86
GCD(1, 86) = 86 / 86
GCD(1, 86) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 422
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 422) = 422
GCD(1, 422) = ( 1 x 422 ) / 422
GCD(1, 422) = 422 / 422
GCD(1, 422) = 1
GCD of 405, 431, 86, 422 is 1
