Given numbers are 990, 243, 147, 115

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 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 147 are 3 x 7 x 7

Prime factors of 115 are 5 x 23

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

Given numbers are 990, 243, 147, 115

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

Apply this formula for all numbers.

Step1:

LCM(990, 243) = 26730

GCD(990, 243) = ( 990 x 243 ) / 26730

= 990 / 243

= 990

Step2:

LCM(9, 147) = 441

GCD(9, 147) = ( 9 x 147 ) / 441

= 9 / 147

= 9

Step3:

LCM(3, 115) = 345

GCD(3, 115) = ( 3 x 115 ) / 345

= 3 / 115

= 3

So, Greatest Common Divisor of 990, 243, 147, 115 is 1
