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

Apply this formula for all numbers.

Step1:

LCM(840, 720) = 5040

GCD(840, 720) = ( 840 x 720 ) / 5040

= 840 / 720

= 840


Step2:

LCM(120, 369) = 14760

GCD(120, 369) = ( 120 x 369 ) / 14760

= 120 / 369

= 120


Step3:

LCM(3, 291) = 291

GCD(3, 291) = ( 3 x 291 ) / 291

= 3 / 291

= 3


So, Greatest Common Divisor of 840, 720, 369, 291 is 3
