Given numbers are 781, 836, 581, 659

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

Apply this formula for all numbers.

Step1:

LCM(781, 836) = 59356

GCD(781, 836) = ( 781 x 836 ) / 59356

= 781 / 836

= 781

Step2:

LCM(11, 581) = 6391

GCD(11, 581) = ( 11 x 581 ) / 6391

= 11 / 581

= 11

Step3:

LCM(1, 659) = 659

GCD(1, 659) = ( 1 x 659 ) / 659

= 1 / 659

= 1

So, Greatest Common Divisor of 781, 836, 581, 659 is 1
