Given numbers are 543, 540, 576, 645

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

Apply this formula for all numbers.

Step1:

LCM(543, 540) = 97740

GCD(543, 540) = ( 543 x 540 ) / 97740

= 543 / 540

= 543

Step2:

LCM(3, 576) = 576

GCD(3, 576) = ( 3 x 576 ) / 576

= 3 / 576

= 3

Step3:

LCM(3, 645) = 645

GCD(3, 645) = ( 3 x 645 ) / 645

= 3 / 645

= 3

So, Greatest Common Divisor of 543, 540, 576, 645 is 3
