The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 987 are 3 x 7 x 47

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

Given numbers are 478, 738, 912, 987

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

Apply this formula for all numbers.

Step1:

LCM(478, 738) = 176382

GCD(478, 738) = ( 478 x 738 ) / 176382

= 478 / 738

= 478

Step2:

LCM(2, 912) = 912

GCD(2, 912) = ( 2 x 912 ) / 912

= 2 / 912

= 2

Step3:

LCM(2, 987) = 1974

GCD(2, 987) = ( 2 x 987 ) / 1974

= 2 / 987

= 2

So, Greatest Common Divisor of 478, 738, 912, 987 is 1
