Given numbers are 406, 304, 831, 816

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 304 are 2 x 2 x 2 x 2 x 19

Prime factors of 831 are 3 x 277

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 406, 304, 831, 816

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

Apply this formula for all numbers.

Step1:

LCM(406, 304) = 61712

GCD(406, 304) = ( 406 x 304 ) / 61712

= 406 / 304

= 406

Step2:

LCM(2, 831) = 1662

GCD(2, 831) = ( 2 x 831 ) / 1662

= 2 / 831

= 2

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 406, 304, 831, 816 is 1
