Given numbers are 406, 828, 805, 249

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 805 are 5 x 7 x 23

Prime factors of 249 are 3 x 83

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

Given numbers are 406, 828, 805, 249

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

Apply this formula for all numbers.

Step1:

LCM(406, 828) = 168084

GCD(406, 828) = ( 406 x 828 ) / 168084

= 406 / 828

= 406

Step2:

LCM(2, 805) = 1610

GCD(2, 805) = ( 2 x 805 ) / 1610

= 2 / 805

= 2

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 406, 828, 805, 249 is 1
