Given numbers are 121, 170, 810, 803

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 170 are 2 x 5 x 17

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

Prime factors of 803 are 11 x 73

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

Given numbers are 121, 170, 810, 803

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

Apply this formula for all numbers.

Step1:

LCM(121, 170) = 20570

GCD(121, 170) = ( 121 x 170 ) / 20570

= 121 / 170

= 121

Step2:

LCM(1, 810) = 810

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

= 1 / 810

= 1

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 121, 170, 810, 803 is 1
