Given numbers are 781, 444, 655

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

Apply this formula for all numbers.

Step1:

LCM(781, 444) = 346764

GCD(781, 444) = ( 781 x 444 ) / 346764

= 781 / 444

= 781

Step2:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 781, 444, 655 is 1
