Given numbers are 990, 803, 311, 247

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 803 are 11 x 73

Prime factors of 311 are 311

Prime factors of 247 are 13 x 19

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

Given numbers are 990, 803, 311, 247

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

Apply this formula for all numbers.

Step1:

LCM(990, 803) = 72270

GCD(990, 803) = ( 990 x 803 ) / 72270

= 990 / 803

= 990

Step2:

LCM(11, 311) = 3421

GCD(11, 311) = ( 11 x 311 ) / 3421

= 11 / 311

= 11

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 990, 803, 311, 247 is 1
