Given numbers are 819, 978, 170, 735

The list of prime factors of all numbers are

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 978 are 2 x 3 x 163

Prime factors of 170 are 2 x 5 x 17

Prime factors of 735 are 3 x 5 x 7 x 7

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

Given numbers are 819, 978, 170, 735

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

Apply this formula for all numbers.

Step1:

LCM(819, 978) = 266994

GCD(819, 978) = ( 819 x 978 ) / 266994

= 819 / 978

= 819

Step2:

LCM(3, 170) = 510

GCD(3, 170) = ( 3 x 170 ) / 510

= 3 / 170

= 3

Step3:

LCM(1, 735) = 735

GCD(1, 735) = ( 1 x 735 ) / 735

= 1 / 735

= 1

So, Greatest Common Divisor of 819, 978, 170, 735 is 1
