Given numbers are 173, 390, 79, 808

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

Apply this formula for all numbers.

Step1:

LCM(173, 390) = 67470

GCD(173, 390) = ( 173 x 390 ) / 67470

= 173 / 390

= 173

Step2:

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

= 1 / 79

= 1

Step3:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

So, Greatest Common Divisor of 173, 390, 79, 808 is 1
