Given numbers are 685, 977, 940

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

Apply this formula for all numbers.

Step1:

LCM(685, 977) = 669245

GCD(685, 977) = ( 685 x 977 ) / 669245

= 685 / 977

= 685

Step2:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

So, Greatest Common Divisor of 685, 977, 940 is 1
