Given numbers are 817, 779, 660, 228

The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

Prime factors of 779 are 19 x 41

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 228 are 2 x 2 x 3 x 19

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

Given numbers are 817, 779, 660, 228

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

Apply this formula for all numbers.

Step1:

LCM(817, 779) = 33497

GCD(817, 779) = ( 817 x 779 ) / 33497

= 817 / 779

= 817

Step2:

LCM(19, 660) = 12540

GCD(19, 660) = ( 19 x 660 ) / 12540

= 19 / 660

= 19

Step3:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

So, Greatest Common Divisor of 817, 779, 660, 228 is 1
