Given numbers are 816, 223, 166, 680

The list of prime factors of all numbers are

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

Prime factors of 223 are 223

Prime factors of 166 are 2 x 83

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 816, 223, 166, 680

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

Apply this formula for all numbers.

Step1:

LCM(816, 223) = 181968

GCD(816, 223) = ( 816 x 223 ) / 181968

= 816 / 223

= 816

Step2:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 816, 223, 166, 680 is 1
