Given numbers are 781, 539, 515, 993

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

Apply this formula for all numbers.

Step1:

LCM(781, 539) = 38269

GCD(781, 539) = ( 781 x 539 ) / 38269

= 781 / 539

= 781

Step2:

LCM(11, 515) = 5665

GCD(11, 515) = ( 11 x 515 ) / 5665

= 11 / 515

= 11

Step3:

LCM(1, 993) = 993

GCD(1, 993) = ( 1 x 993 ) / 993

= 1 / 993

= 1

So, Greatest Common Divisor of 781, 539, 515, 993 is 1
