Given numbers are 781, 555, 520, 587

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

Apply this formula for all numbers.

Step1:

LCM(781, 555) = 433455

GCD(781, 555) = ( 781 x 555 ) / 433455

= 781 / 555

= 781

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 587) = 587

GCD(1, 587) = ( 1 x 587 ) / 587

= 1 / 587

= 1

So, Greatest Common Divisor of 781, 555, 520, 587 is 1
