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

Apply this formula for all numbers.

Step1:

LCM(389, 343) = 133427

GCD(389, 343) = ( 389 x 343 ) / 133427

= 389 / 343

= 389

Step2:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 389, 343, 788, 765 is 1
