Given numbers are 781, 662, 210

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

Apply this formula for all numbers.

Step1:

LCM(781, 662) = 517022

GCD(781, 662) = ( 781 x 662 ) / 517022

= 781 / 662

= 781

Step2:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

So, Greatest Common Divisor of 781, 662, 210 is 1
