Given numbers are 198, 978, 718, 819

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

Apply this formula for all numbers.

Step1:

LCM(198, 978) = 32274

GCD(198, 978) = ( 198 x 978 ) / 32274

= 198 / 978

= 198

Step2:

LCM(6, 718) = 2154

GCD(6, 718) = ( 6 x 718 ) / 2154

= 6 / 718

= 6

Step3:

LCM(2, 819) = 1638

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

= 2 / 819

= 2

So, Greatest Common Divisor of 198, 978, 718, 819 is 1
