Given numbers are 781, 865, 436

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

Apply this formula for all numbers.

Step1:

LCM(781, 865) = 675565

GCD(781, 865) = ( 781 x 865 ) / 675565

= 781 / 865

= 781

Step2:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

So, Greatest Common Divisor of 781, 865, 436 is 1
