Given numbers are 100, 978, 558

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

Apply this formula for all numbers.

Step1:

LCM(100, 978) = 48900

GCD(100, 978) = ( 100 x 978 ) / 48900

= 100 / 978

= 100

Step2:

LCM(2, 558) = 558

GCD(2, 558) = ( 2 x 558 ) / 558

= 2 / 558

= 2

So, Greatest Common Divisor of 100, 978, 558 is 2
