Given numbers are 685, 651, 338

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

Apply this formula for all numbers.

Step1:

LCM(685, 651) = 445935

GCD(685, 651) = ( 685 x 651 ) / 445935

= 685 / 651

= 685

Step2:

LCM(1, 338) = 338

GCD(1, 338) = ( 1 x 338 ) / 338

= 1 / 338

= 1

So, Greatest Common Divisor of 685, 651, 338 is 1
