We found the divisors of 920, 951, 181, 170 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 920, 951, 181, 170 is 1.

Therefore, GCD of numbers 920, 951, 181, 170 is 1

Given Input Data is 920, 951, 181, 170

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

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 951 is 3 x 317

Prime Factorization of 181 is 181

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(920, 951) = 874920

GCD(920, 951) = ( 920 x 951 ) / 874920

GCD(920, 951) = 874920 / 874920

GCD(920, 951) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 181

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

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

GCD(1, 181) = 181 / 181

GCD(1, 181) = 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 920, 951, 181, 170 is 1
