Given numbers are 558, 654, 421, 173

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

Apply this formula for all numbers.

Step1:

LCM(558, 654) = 60822

GCD(558, 654) = ( 558 x 654 ) / 60822

= 558 / 654

= 558

Step2:

LCM(6, 421) = 2526

GCD(6, 421) = ( 6 x 421 ) / 2526

= 6 / 421

= 6

Step3:

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

= 1 / 173

= 1

So, Greatest Common Divisor of 558, 654, 421, 173 is 1
