Given numbers are 543, 663, 239, 891

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

Apply this formula for all numbers.

Step1:

LCM(543, 663) = 120003

GCD(543, 663) = ( 543 x 663 ) / 120003

= 543 / 663

= 543

Step2:

LCM(3, 239) = 717

GCD(3, 239) = ( 3 x 239 ) / 717

= 3 / 239

= 3

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 543, 663, 239, 891 is 1
