Given numbers are 808, 459, 259, 644

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

Apply this formula for all numbers.

Step1:

LCM(808, 459) = 370872

GCD(808, 459) = ( 808 x 459 ) / 370872

= 808 / 459

= 808

Step2:

LCM(1, 259) = 259

GCD(1, 259) = ( 1 x 259 ) / 259

= 1 / 259

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 808, 459, 259, 644 is 1
