Given numbers are 685, 213, 326, 168

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

Apply this formula for all numbers.

Step1:

LCM(685, 213) = 145905

GCD(685, 213) = ( 685 x 213 ) / 145905

= 685 / 213

= 685

Step2:

LCM(1, 326) = 326

GCD(1, 326) = ( 1 x 326 ) / 326

= 1 / 326

= 1

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 685, 213, 326, 168 is 1
