Given numbers are 406, 925, 816, 309

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 925 are 5 x 5 x 37

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

Prime factors of 309 are 3 x 103

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

Given numbers are 406, 925, 816, 309

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

Apply this formula for all numbers.

Step1:

LCM(406, 925) = 375550

GCD(406, 925) = ( 406 x 925 ) / 375550

= 406 / 925

= 406

Step2:

LCM(1, 816) = 816

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

= 1 / 816

= 1

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 406, 925, 816, 309 is 1
