Given numbers are 806, 279, 912, 639

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, 912) = 28272

GCD(31, 912) = ( 31 x 912 ) / 28272

= 31 / 912

= 31

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 806, 279, 912, 639 is 1
