Given numbers are 685, 705, 636, 211

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 705 are 3 x 5 x 47

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 211 are 211

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

Given numbers are 685, 705, 636, 211

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

Apply this formula for all numbers.

Step1:

LCM(685, 705) = 96585

GCD(685, 705) = ( 685 x 705 ) / 96585

= 685 / 705

= 685

Step2:

LCM(5, 636) = 3180

GCD(5, 636) = ( 5 x 636 ) / 3180

= 5 / 636

= 5

Step3:

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

= 1 / 211

= 1

So, Greatest Common Divisor of 685, 705, 636, 211 is 1
