Given numbers are 388, 808, 761, 765

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

Apply this formula for all numbers.

Step1:

LCM(388, 808) = 78376

GCD(388, 808) = ( 388 x 808 ) / 78376

= 388 / 808

= 388

Step2:

LCM(4, 761) = 3044

GCD(4, 761) = ( 4 x 761 ) / 3044

= 4 / 761

= 4

Step3:

LCM(1, 765) = 765

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

= 1 / 765

= 1

So, Greatest Common Divisor of 388, 808, 761, 765 is 1
