Given numbers are 578, 398, 195, 815

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

Apply this formula for all numbers.

Step1:

LCM(578, 398) = 115022

GCD(578, 398) = ( 578 x 398 ) / 115022

= 578 / 398

= 578

Step2:

LCM(2, 195) = 390

GCD(2, 195) = ( 2 x 195 ) / 390

= 2 / 195

= 2

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 578, 398, 195, 815 is 1
