Given numbers are 990, 921, 32, 388

The list of prime factors of all numbers are

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 921 are 3 x 307

Prime factors of 32 are 2 x 2 x 2 x 2 x 2

Prime factors of 388 are 2 x 2 x 97

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

Given numbers are 990, 921, 32, 388

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

Apply this formula for all numbers.

Step1:

LCM(990, 921) = 303930

GCD(990, 921) = ( 990 x 921 ) / 303930

= 990 / 921

= 990

Step2:

LCM(3, 32) = 96

GCD(3, 32) = ( 3 x 32 ) / 96

= 3 / 32

= 3

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 990, 921, 32, 388 is 1
