Given numbers are 685, 477, 360, 247

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 477 are 3 x 3 x 53

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 247 are 13 x 19

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

Given numbers are 685, 477, 360, 247

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

Apply this formula for all numbers.

Step1:

LCM(685, 477) = 326745

GCD(685, 477) = ( 685 x 477 ) / 326745

= 685 / 477

= 685

Step2:

LCM(1, 360) = 360

GCD(1, 360) = ( 1 x 360 ) / 360

= 1 / 360

= 1

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 685, 477, 360, 247 is 1
