Given numbers are 820, 321, 76

The list of prime factors of all numbers are

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

Prime factors of 321 are 3 x 107

Prime factors of 76 are 2 x 2 x 19

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

Given numbers are 820, 321, 76

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

Apply this formula for all numbers.

Step1:

LCM(820, 321) = 263220

GCD(820, 321) = ( 820 x 321 ) / 263220

= 820 / 321

= 820

Step2:

LCM(1, 76) = 76

GCD(1, 76) = ( 1 x 76 ) / 76

= 1 / 76

= 1

So, Greatest Common Divisor of 820, 321, 76 is 1
