Given numbers are 806, 279, 457, 778

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

Apply this formula for all numbers.

Step1:

LCM(806, 279) = 7254

GCD(806, 279) = ( 806 x 279 ) / 7254

= 806 / 279

= 806

Step2:

LCM(31, 457) = 14167

GCD(31, 457) = ( 31 x 457 ) / 14167

= 31 / 457

= 31

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 806, 279, 457, 778 is 1
