We found the divisors of 217, 207, 75, 258 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 217, 207, 75, 258 is 1.

Therefore, GCD of numbers 217, 207, 75, 258 is 1

Given Input Data is 217, 207, 75, 258

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

Prime Factorization of 217 is 7 x 31

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 258 is 2 x 3 x 43

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(217, 207) = 44919

GCD(217, 207) = ( 217 x 207 ) / 44919

GCD(217, 207) = 44919 / 44919

GCD(217, 207) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 75

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

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

GCD(1, 75) = 75 / 75

GCD(1, 75) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 258

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

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

GCD(1, 258) = 258 / 258

GCD(1, 258) = 1

GCD of 217, 207, 75, 258 is 1
