Given numbers are 978, 310, 819

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

Apply this formula for all numbers.

Step1:

LCM(978, 310) = 151590

GCD(978, 310) = ( 978 x 310 ) / 151590

= 978 / 310

= 978

Step2:

LCM(2, 819) = 1638

GCD(2, 819) = ( 2 x 819 ) / 1638

= 2 / 819

= 2

So, Greatest Common Divisor of 978, 310, 819 is 1
