Given numbers are 254, 678, 814, 819

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

Apply this formula for all numbers.

Step1:

LCM(254, 678) = 86106

GCD(254, 678) = ( 254 x 678 ) / 86106

= 254 / 678

= 254

Step2:

LCM(2, 814) = 814

GCD(2, 814) = ( 2 x 814 ) / 814

= 2 / 814

= 2

Step3:

LCM(2, 819) = 1638

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

= 2 / 819

= 2

So, Greatest Common Divisor of 254, 678, 814, 819 is 1
