Given numbers are 990, 788, 228, 231

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 788 are 2 x 2 x 197

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 990, 788, 228, 231

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

Apply this formula for all numbers.

Step1:

LCM(990, 788) = 390060

GCD(990, 788) = ( 990 x 788 ) / 390060

= 990 / 788

= 990

Step2:

LCM(2, 228) = 228

GCD(2, 228) = ( 2 x 228 ) / 228

= 2 / 228

= 2

Step3:

LCM(2, 231) = 462

GCD(2, 231) = ( 2 x 231 ) / 462

= 2 / 231

= 2

So, Greatest Common Divisor of 990, 788, 228, 231 is 1
