Given numbers are 170, 855, 648, 829

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 829 are 829

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

Given numbers are 170, 855, 648, 829

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

Apply this formula for all numbers.

Step1:

LCM(170, 855) = 29070

GCD(170, 855) = ( 170 x 855 ) / 29070

= 170 / 855

= 170

Step2:

LCM(5, 648) = 3240

GCD(5, 648) = ( 5 x 648 ) / 3240

= 5 / 648

= 5

Step3:

LCM(1, 829) = 829

GCD(1, 829) = ( 1 x 829 ) / 829

= 1 / 829

= 1

So, Greatest Common Divisor of 170, 855, 648, 829 is 1
