Given numbers are 729, 252, 484, 643

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

Apply this formula for all numbers.

Step1:

LCM(729, 252) = 20412

GCD(729, 252) = ( 729 x 252 ) / 20412

= 729 / 252

= 729

Step2:

LCM(9, 484) = 4356

GCD(9, 484) = ( 9 x 484 ) / 4356

= 9 / 484

= 9

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 729, 252, 484, 643 is 1
