Given numbers are 729, 237, 810, 989

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

Apply this formula for all numbers.

Step1:

LCM(729, 237) = 57591

GCD(729, 237) = ( 729 x 237 ) / 57591

= 729 / 237

= 729

Step2:

LCM(3, 810) = 810

GCD(3, 810) = ( 3 x 810 ) / 810

= 3 / 810

= 3

Step3:

LCM(3, 989) = 2967

GCD(3, 989) = ( 3 x 989 ) / 2967

= 3 / 989

= 3

So, Greatest Common Divisor of 729, 237, 810, 989 is 1
