Given numbers are 555, 665, 998, 243

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

Apply this formula for all numbers.

Step1:

LCM(555, 665) = 73815

GCD(555, 665) = ( 555 x 665 ) / 73815

= 555 / 665

= 555

Step2:

LCM(5, 998) = 4990

GCD(5, 998) = ( 5 x 998 ) / 4990

= 5 / 998

= 5

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 555, 665, 998, 243 is 1
