Given numbers are 612, 816, 642, 543

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

Apply this formula for all numbers.

Step1:

LCM(612, 816) = 2448

GCD(612, 816) = ( 612 x 816 ) / 2448

= 612 / 816

= 612

Step2:

LCM(204, 642) = 21828

GCD(204, 642) = ( 204 x 642 ) / 21828

= 204 / 642

= 204

Step3:

LCM(6, 543) = 1086

GCD(6, 543) = ( 6 x 543 ) / 1086

= 6 / 543

= 6

So, Greatest Common Divisor of 612, 816, 642, 543 is 3
