Given numbers are 815, 170, 440, 609

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 170 are 2 x 5 x 17

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 609 are 3 x 7 x 29

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 815, 170, 440, 609

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(815, 170) = 27710

GCD(815, 170) = ( 815 x 170 ) / 27710

= 815 / 170

= 815

Step2:

LCM(5, 440) = 440

GCD(5, 440) = ( 5 x 440 ) / 440

= 5 / 440

= 5

Step3:

LCM(5, 609) = 3045

GCD(5, 609) = ( 5 x 609 ) / 3045

= 5 / 609

= 5

So, Greatest Common Divisor of 815, 170, 440, 609 is 1
