Given numbers are 389, 531, 343, 693

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

Apply this formula for all numbers.

Step1:

LCM(389, 531) = 206559

GCD(389, 531) = ( 389 x 531 ) / 206559

= 389 / 531

= 389

Step2:

LCM(1, 343) = 343

GCD(1, 343) = ( 1 x 343 ) / 343

= 1 / 343

= 1

Step3:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

So, Greatest Common Divisor of 389, 531, 343, 693 is 1
