Given numbers are 685, 353, 356, 602

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

Apply this formula for all numbers.

Step1:

LCM(685, 353) = 241805

GCD(685, 353) = ( 685 x 353 ) / 241805

= 685 / 353

= 685

Step2:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

Step3:

LCM(1, 602) = 602

GCD(1, 602) = ( 1 x 602 ) / 602

= 1 / 602

= 1

So, Greatest Common Divisor of 685, 353, 356, 602 is 1
