Given numbers are 665, 225, 382, 809

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

Apply this formula for all numbers.

Step1:

LCM(665, 225) = 29925

GCD(665, 225) = ( 665 x 225 ) / 29925

= 665 / 225

= 665

Step2:

LCM(5, 382) = 1910

GCD(5, 382) = ( 5 x 382 ) / 1910

= 5 / 382

= 5

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 665, 225, 382, 809 is 1
