Given numbers are 693, 723, 781, 839

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

Apply this formula for all numbers.

Step1:

LCM(693, 723) = 167013

GCD(693, 723) = ( 693 x 723 ) / 167013

= 693 / 723

= 693

Step2:

LCM(3, 781) = 2343

GCD(3, 781) = ( 3 x 781 ) / 2343

= 3 / 781

= 3

Step3:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

So, Greatest Common Divisor of 693, 723, 781, 839 is 1
