Given numbers are 409, 810, 867, 605

The list of prime factors of all numbers are

Prime factors of 409 are 409

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

Prime factors of 867 are 3 x 17 x 17

Prime factors of 605 are 5 x 11 x 11

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

Given numbers are 409, 810, 867, 605

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

Apply this formula for all numbers.

Step1:

LCM(409, 810) = 331290

GCD(409, 810) = ( 409 x 810 ) / 331290

= 409 / 810

= 409

Step2:

LCM(1, 867) = 867

GCD(1, 867) = ( 1 x 867 ) / 867

= 1 / 867

= 1

Step3:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

So, Greatest Common Divisor of 409, 810, 867, 605 is 1
