Given numbers are 781, 289, 287, 544

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

Apply this formula for all numbers.

Step1:

LCM(781, 289) = 225709

GCD(781, 289) = ( 781 x 289 ) / 225709

= 781 / 289

= 781

Step2:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

Step3:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

So, Greatest Common Divisor of 781, 289, 287, 544 is 1
