Given numbers are 990, 855, 803, 558

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 855 are 3 x 3 x 5 x 19

Prime factors of 803 are 11 x 73

Prime factors of 558 are 2 x 3 x 3 x 31

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

Given numbers are 990, 855, 803, 558

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

Apply this formula for all numbers.

Step1:

LCM(990, 855) = 18810

GCD(990, 855) = ( 990 x 855 ) / 18810

= 990 / 855

= 990

Step2:

LCM(45, 803) = 36135

GCD(45, 803) = ( 45 x 803 ) / 36135

= 45 / 803

= 45

Step3:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

So, Greatest Common Divisor of 990, 855, 803, 558 is 1
