So the Greatest Common Divisior 257, 154, 176, 170 is 1.

Therefore, GCD of numbers 257, 154, 176, 170 is 1

Given Input Data is 257, 154, 176, 170

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

Prime Factorization of 257 is 257

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 176 is 2 x 2 x 2 x 2 x 11

Prime Factorization of 170 is 2 x 5 x 17

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(257, 154) = 39578

GCD(257, 154) = ( 257 x 154 ) / 39578

GCD(257, 154) = 39578 / 39578

GCD(257, 154) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 176

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

LCM(1, 176) = 176

GCD(1, 176) = ( 1 x 176 ) / 176

GCD(1, 176) = 176 / 176

GCD(1, 176) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 170

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

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

GCD(1, 170) = 170 / 170

GCD(1, 170) = 1

GCD of 257, 154, 176, 170 is 1
