Given numbers are 389, 561, 393, 167

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

Apply this formula for all numbers.

Step1:

LCM(389, 561) = 218229

GCD(389, 561) = ( 389 x 561 ) / 218229

= 389 / 561

= 389

Step2:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

Step3:

LCM(1, 167) = 167

GCD(1, 167) = ( 1 x 167 ) / 167

= 1 / 167

= 1

So, Greatest Common Divisor of 389, 561, 393, 167 is 1
