Given numbers are 781, 213, 555

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

Apply this formula for all numbers.

Step1:

LCM(781, 213) = 2343

GCD(781, 213) = ( 781 x 213 ) / 2343

= 781 / 213

= 781

Step2:

LCM(71, 555) = 39405

GCD(71, 555) = ( 71 x 555 ) / 39405

= 71 / 555

= 71

So, Greatest Common Divisor of 781, 213, 555 is 1
