Given numbers are 543, 285, 840, 624

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

Apply this formula for all numbers.

Step1:

LCM(543, 285) = 51585

GCD(543, 285) = ( 543 x 285 ) / 51585

= 543 / 285

= 543

Step2:

LCM(3, 840) = 840

GCD(3, 840) = ( 3 x 840 ) / 840

= 3 / 840

= 3

Step3:

LCM(3, 624) = 624

GCD(3, 624) = ( 3 x 624 ) / 624

= 3 / 624

= 3

So, Greatest Common Divisor of 543, 285, 840, 624 is 3
