Given numbers are 209, 308, 235, 812

The list of prime factors of all numbers are

Prime factors of 209 are 11 x 19

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 235 are 5 x 47

Prime factors of 812 are 2 x 2 x 7 x 29

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

Given numbers are 209, 308, 235, 812

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

Apply this formula for all numbers.

Step1:

LCM(209, 308) = 5852

GCD(209, 308) = ( 209 x 308 ) / 5852

= 209 / 308

= 209

Step2:

LCM(11, 235) = 2585

GCD(11, 235) = ( 11 x 235 ) / 2585

= 11 / 235

= 11

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 209, 308, 235, 812 is 1
