We found the divisors of 215, 257, 460, 185 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 215, 257, 460, 185 is 1.

Therefore, GCD of numbers 215, 257, 460, 185 is 1

Given Input Data is 215, 257, 460, 185

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 215 is 5 x 43

Prime Factorization of 257 is 257

Prime Factorization of 460 is 2 x 2 x 5 x 23

Prime Factorization of 185 is 5 x 37

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(215, 257) = 55255

GCD(215, 257) = ( 215 x 257 ) / 55255

GCD(215, 257) = 55255 / 55255

GCD(215, 257) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 460

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 460) = 460

GCD(1, 460) = ( 1 x 460 ) / 460

GCD(1, 460) = 460 / 460

GCD(1, 460) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 185

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 185) = 185

GCD(1, 185) = ( 1 x 185 ) / 185

GCD(1, 185) = 185 / 185

GCD(1, 185) = 1

GCD of 215, 257, 460, 185 is 1
