Given numbers are 729, 972, 553, 645

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

Apply this formula for all numbers.

Step1:

LCM(729, 972) = 2916

GCD(729, 972) = ( 729 x 972 ) / 2916

= 729 / 972

= 729

Step2:

LCM(243, 553) = 134379

GCD(243, 553) = ( 243 x 553 ) / 134379

= 243 / 553

= 243

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 729, 972, 553, 645 is 1
