Given numbers are 788, 648, 398, 389

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

Apply this formula for all numbers.

Step1:

LCM(788, 648) = 127656

GCD(788, 648) = ( 788 x 648 ) / 127656

= 788 / 648

= 788

Step2:

LCM(4, 398) = 796

GCD(4, 398) = ( 4 x 398 ) / 796

= 4 / 398

= 4

Step3:

LCM(2, 389) = 778

GCD(2, 389) = ( 2 x 389 ) / 778

= 2 / 389

= 2

So, Greatest Common Divisor of 788, 648, 398, 389 is 1
