Given numbers are 855, 795, 788, 393

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

Apply this formula for all numbers.

Step1:

LCM(855, 795) = 45315

GCD(855, 795) = ( 855 x 795 ) / 45315

= 855 / 795

= 855

Step2:

LCM(15, 788) = 11820

GCD(15, 788) = ( 15 x 788 ) / 11820

= 15 / 788

= 15

Step3:

LCM(1, 393) = 393

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

= 1 / 393

= 1

So, Greatest Common Divisor of 855, 795, 788, 393 is 1
