Given numbers are 255, 890, 363, 990

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 890 are 2 x 5 x 89

Prime factors of 363 are 3 x 11 x 11

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

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

Given numbers are 255, 890, 363, 990

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

Apply this formula for all numbers.

Step1:

LCM(255, 890) = 45390

GCD(255, 890) = ( 255 x 890 ) / 45390

= 255 / 890

= 255

Step2:

LCM(5, 363) = 1815

GCD(5, 363) = ( 5 x 363 ) / 1815

= 5 / 363

= 5

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 255, 890, 363, 990 is 1
