Given numbers are 721, 840, 539

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

Apply this formula for all numbers.

Step1:

LCM(721, 840) = 86520

GCD(721, 840) = ( 721 x 840 ) / 86520

= 721 / 840

= 721

Step2:

LCM(7, 539) = 539

GCD(7, 539) = ( 7 x 539 ) / 539

= 7 / 539

= 7

So, Greatest Common Divisor of 721, 840, 539 is 7
