Therefore, GCD of numbers 170, 845, 36, 545 is 1

Given Input Data is 170, 845, 36, 545

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

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 36 is 2 x 2 x 3 x 3

Prime Factorization of 545 is 5 x 109

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(170, 845) = 28730

GCD(170, 845) = ( 170 x 845 ) / 28730

GCD(170, 845) = 143650 / 28730

GCD(170, 845) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 36

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

LCM(5, 36) = 180

GCD(5, 36) = ( 5 x 36 ) / 180

GCD(5, 36) = 180 / 180

GCD(5, 36) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 545

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

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

GCD(1, 545) = 545 / 545

GCD(1, 545) = 1

GCD of 170, 845, 36, 545 is 1
