Given numbers are 685, 357, 210, 459

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 357 are 3 x 7 x 17

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 459 are 3 x 3 x 3 x 17

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

Given numbers are 685, 357, 210, 459

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

Apply this formula for all numbers.

Step1:

LCM(685, 357) = 244545

GCD(685, 357) = ( 685 x 357 ) / 244545

= 685 / 357

= 685

Step2:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

Step3:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

So, Greatest Common Divisor of 685, 357, 210, 459 is 1
