The list of prime factors of all numbers are

Prime factors of 197 are 197

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

Prime factors of 178 are 2 x 89

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 197, 440, 178, 816

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

Apply this formula for all numbers.

Step1:

LCM(197, 440) = 86680

GCD(197, 440) = ( 197 x 440 ) / 86680

= 197 / 440

= 197

Step2:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 197, 440, 178, 816 is 1
