Given numbers are 685, 385, 980, 163

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

Apply this formula for all numbers.

Step1:

LCM(685, 385) = 52745

GCD(685, 385) = ( 685 x 385 ) / 52745

= 685 / 385

= 685

Step2:

LCM(5, 980) = 980

GCD(5, 980) = ( 5 x 980 ) / 980

= 5 / 980

= 5

Step3:

LCM(5, 163) = 815

GCD(5, 163) = ( 5 x 163 ) / 815

= 5 / 163

= 5

So, Greatest Common Divisor of 685, 385, 980, 163 is 1
