Given numbers are 817, 820, 381, 576

The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

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

Prime factors of 381 are 3 x 127

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 817, 820, 381, 576

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

Apply this formula for all numbers.

Step1:

LCM(817, 820) = 669940

GCD(817, 820) = ( 817 x 820 ) / 669940

= 817 / 820

= 817

Step2:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

Step3:

LCM(1, 576) = 576

GCD(1, 576) = ( 1 x 576 ) / 576

= 1 / 576

= 1

So, Greatest Common Divisor of 817, 820, 381, 576 is 1
