Given numbers are 189, 909, 87, 809

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

Apply this formula for all numbers.

Step1:

LCM(189, 909) = 19089

GCD(189, 909) = ( 189 x 909 ) / 19089

= 189 / 909

= 189

Step2:

LCM(9, 87) = 261

GCD(9, 87) = ( 9 x 87 ) / 261

= 9 / 87

= 9

Step3:

LCM(3, 809) = 2427

GCD(3, 809) = ( 3 x 809 ) / 2427

= 3 / 809

= 3

So, Greatest Common Divisor of 189, 909, 87, 809 is 1
