Given numbers are 518, 623, 872, 729

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

Apply this formula for all numbers.

Step1:

LCM(518, 623) = 46102

GCD(518, 623) = ( 518 x 623 ) / 46102

= 518 / 623

= 518

Step2:

LCM(7, 872) = 6104

GCD(7, 872) = ( 7 x 872 ) / 6104

= 7 / 872

= 7

Step3:

LCM(1, 729) = 729

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

= 1 / 729

= 1

So, Greatest Common Divisor of 518, 623, 872, 729 is 1
