Given numbers are 558, 639, 285, 904

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

Apply this formula for all numbers.

Step1:

LCM(558, 639) = 39618

GCD(558, 639) = ( 558 x 639 ) / 39618

= 558 / 639

= 558

Step2:

LCM(9, 285) = 855

GCD(9, 285) = ( 9 x 285 ) / 855

= 9 / 285

= 9

Step3:

LCM(3, 904) = 2712

GCD(3, 904) = ( 3 x 904 ) / 2712

= 3 / 904

= 3

So, Greatest Common Divisor of 558, 639, 285, 904 is 1
