Given numbers are 645, 389, 257, 184

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

Apply this formula for all numbers.

Step1:

LCM(645, 389) = 250905

GCD(645, 389) = ( 645 x 389 ) / 250905

= 645 / 389

= 645

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 184) = 184

GCD(1, 184) = ( 1 x 184 ) / 184

= 1 / 184

= 1

So, Greatest Common Divisor of 645, 389, 257, 184 is 1
