Given numbers are 660, 819, 683, 209

The list of prime factors of all numbers are

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

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 683 are 683

Prime factors of 209 are 11 x 19

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

Given numbers are 660, 819, 683, 209

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

Apply this formula for all numbers.

Step1:

LCM(660, 819) = 180180

GCD(660, 819) = ( 660 x 819 ) / 180180

= 660 / 819

= 660

Step2:

LCM(3, 683) = 2049

GCD(3, 683) = ( 3 x 683 ) / 2049

= 3 / 683

= 3

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 660, 819, 683, 209 is 1
