Given numbers are 943, 656, 643, 723

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

Apply this formula for all numbers.

Step1:

LCM(943, 656) = 15088

GCD(943, 656) = ( 943 x 656 ) / 15088

= 943 / 656

= 943

Step2:

LCM(41, 643) = 26363

GCD(41, 643) = ( 41 x 643 ) / 26363

= 41 / 643

= 41

Step3:

LCM(1, 723) = 723

GCD(1, 723) = ( 1 x 723 ) / 723

= 1 / 723

= 1

So, Greatest Common Divisor of 943, 656, 643, 723 is 1
