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
