Given numbers are 723, 691, 643, 336

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

Apply this formula for all numbers.

Step1:

LCM(723, 691) = 499593

GCD(723, 691) = ( 723 x 691 ) / 499593

= 723 / 691

= 723

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 336) = 336

GCD(1, 336) = ( 1 x 336 ) / 336

= 1 / 336

= 1

So, Greatest Common Divisor of 723, 691, 643, 336 is 1
