We found the divisors of 161, 159, 570, 209 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 161, 159, 570, 209 is 1.

Therefore, GCD of numbers 161, 159, 570, 209 is 1

Given Input Data is 161, 159, 570, 209

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

Prime Factorization of 161 is 7 x 23

Prime Factorization of 159 is 3 x 53

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 209 is 11 x 19

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(161, 159) = 25599

GCD(161, 159) = ( 161 x 159 ) / 25599

GCD(161, 159) = 25599 / 25599

GCD(161, 159) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 570

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

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

GCD(1, 570) = 570 / 570

GCD(1, 570) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 209

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

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

GCD(1, 209) = 209 / 209

GCD(1, 209) = 1

GCD of 161, 159, 570, 209 is 1
