The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 395 are 5 x 79

Prime factors of 474 are 2 x 3 x 79

Prime factors of 178 are 2 x 89

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

Given numbers are 987, 395, 474, 178

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

Apply this formula for all numbers.

Step1:

LCM(987, 395) = 389865

GCD(987, 395) = ( 987 x 395 ) / 389865

= 987 / 395

= 987

Step2:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

Step3:

LCM(1, 178) = 178

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

= 1 / 178

= 1

So, Greatest Common Divisor of 987, 395, 474, 178 is 1
