Given numbers are 165, 310, 816, 428

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 310 are 2 x 5 x 31

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

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 165, 310, 816, 428

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

Apply this formula for all numbers.

Step1:

LCM(165, 310) = 10230

GCD(165, 310) = ( 165 x 310 ) / 10230

= 165 / 310

= 165

Step2:

LCM(5, 816) = 4080

GCD(5, 816) = ( 5 x 816 ) / 4080

= 5 / 816

= 5

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 165, 310, 816, 428 is 1
