Given numbers are 543, 981, 16, 628

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

Apply this formula for all numbers.

Step1:

LCM(543, 981) = 177561

GCD(543, 981) = ( 543 x 981 ) / 177561

= 543 / 981

= 543

Step2:

LCM(3, 16) = 48

GCD(3, 16) = ( 3 x 16 ) / 48

= 3 / 16

= 3

Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

So, Greatest Common Divisor of 543, 981, 16, 628 is 1
