Given numbers are 820, 351, 310, 669

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 310 are 2 x 5 x 31

Prime factors of 669 are 3 x 223

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

Given numbers are 820, 351, 310, 669

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

Apply this formula for all numbers.

Step1:

LCM(820, 351) = 287820

GCD(820, 351) = ( 820 x 351 ) / 287820

= 820 / 351

= 820

Step2:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1

Step3:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 820, 351, 310, 669 is 1
