Given numbers are 558, 198, 660, 903

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

Apply this formula for all numbers.

Step1:

LCM(558, 198) = 6138

GCD(558, 198) = ( 558 x 198 ) / 6138

= 558 / 198

= 558

Step2:

LCM(18, 660) = 1980

GCD(18, 660) = ( 18 x 660 ) / 1980

= 18 / 660

= 18

Step3:

LCM(6, 903) = 1806

GCD(6, 903) = ( 6 x 903 ) / 1806

= 6 / 903

= 6

So, Greatest Common Divisor of 558, 198, 660, 903 is 3
