Given numbers are 170, 611, 166, 815

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 611 are 13 x 47

Prime factors of 166 are 2 x 83

Prime factors of 815 are 5 x 163

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

Given numbers are 170, 611, 166, 815

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

Apply this formula for all numbers.

Step1:

LCM(170, 611) = 103870

GCD(170, 611) = ( 170 x 611 ) / 103870

= 170 / 611

= 170

Step2:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 170, 611, 166, 815 is 1
