The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 470 are 2 x 5 x 47

Prime factors of 209 are 11 x 19

Prime factors of 436 are 2 x 2 x 109

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

Given numbers are 685, 470, 209, 436

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

Apply this formula for all numbers.

Step1:

LCM(685, 470) = 64390

GCD(685, 470) = ( 685 x 470 ) / 64390

= 685 / 470

= 685

Step2:

LCM(5, 209) = 1045

GCD(5, 209) = ( 5 x 209 ) / 1045

= 5 / 209

= 5

Step3:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

So, Greatest Common Divisor of 685, 470, 209, 436 is 1
