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

Apply this formula for all numbers.

Step1:

LCM(558, 999) = 61938

GCD(558, 999) = ( 558 x 999 ) / 61938

= 558 / 999

= 558

Step2:

LCM(9, 425) = 3825

GCD(9, 425) = ( 9 x 425 ) / 3825

= 9 / 425

= 9

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 558, 999, 425, 978 is 1
