Given numbers are 465, 810, 281, 189

The list of prime factors of all numbers are

Prime factors of 465 are 3 x 5 x 31

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

Prime factors of 281 are 281

Prime factors of 189 are 3 x 3 x 3 x 7

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

Given numbers are 465, 810, 281, 189

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

Apply this formula for all numbers.

Step1:

LCM(465, 810) = 25110

GCD(465, 810) = ( 465 x 810 ) / 25110

= 465 / 810

= 465

Step2:

LCM(15, 281) = 4215

GCD(15, 281) = ( 15 x 281 ) / 4215

= 15 / 281

= 15

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 465, 810, 281, 189 is 1
