Given numbers are 685, 313, 393, 479

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

Apply this formula for all numbers.

Step1:

LCM(685, 313) = 214405

GCD(685, 313) = ( 685 x 313 ) / 214405

= 685 / 313

= 685

Step2:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

Step3:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

So, Greatest Common Divisor of 685, 313, 393, 479 is 1
