We found the divisors of 165, 245, 57, 250 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 165, 245, 57, 250 is 1.

Therefore, GCD of numbers 165, 245, 57, 250 is 1

Given Input Data is 165, 245, 57, 250

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

Prime Factorization of 165 is 3 x 5 x 11

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 57 is 3 x 19

Prime Factorization of 250 is 2 x 5 x 5 x 5

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(165, 245) = 8085

GCD(165, 245) = ( 165 x 245 ) / 8085

GCD(165, 245) = 40425 / 8085

GCD(165, 245) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 57

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

LCM(5, 57) = 285

GCD(5, 57) = ( 5 x 57 ) / 285

GCD(5, 57) = 285 / 285

GCD(5, 57) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 250

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

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

GCD(1, 250) = 250 / 250

GCD(1, 250) = 1

GCD of 165, 245, 57, 250 is 1
