Given numbers are 831, 905, 386, 729

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

Apply this formula for all numbers.

Step1:

LCM(831, 905) = 752055

GCD(831, 905) = ( 831 x 905 ) / 752055

= 831 / 905

= 831

Step2:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

Step3:

LCM(1, 729) = 729

GCD(1, 729) = ( 1 x 729 ) / 729

= 1 / 729

= 1

So, Greatest Common Divisor of 831, 905, 386, 729 is 1
