Given numbers are 991, 442, 810, 115

The list of prime factors of all numbers are

Prime factors of 991 are 991

Prime factors of 442 are 2 x 13 x 17

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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 991, 442, 810, 115

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

Apply this formula for all numbers.

Step1:

LCM(991, 442) = 438022

GCD(991, 442) = ( 991 x 442 ) / 438022

= 991 / 442

= 991

Step2:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 991, 442, 810, 115 is 1
