Given numbers are 389, 145, 243, 904

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

Apply this formula for all numbers.

Step1:

LCM(389, 145) = 56405

GCD(389, 145) = ( 389 x 145 ) / 56405

= 389 / 145

= 389

Step2:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

Step3:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

So, Greatest Common Divisor of 389, 145, 243, 904 is 1
