Given numbers are 558, 243, 132, 643

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

Apply this formula for all numbers.

Step1:

LCM(558, 243) = 15066

GCD(558, 243) = ( 558 x 243 ) / 15066

= 558 / 243

= 558

Step2:

LCM(9, 132) = 396

GCD(9, 132) = ( 9 x 132 ) / 396

= 9 / 132

= 9

Step3:

LCM(3, 643) = 1929

GCD(3, 643) = ( 3 x 643 ) / 1929

= 3 / 643

= 3

So, Greatest Common Divisor of 558, 243, 132, 643 is 1
