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

Apply this formula for all numbers.

Step1:

LCM(378, 399) = 7182

GCD(378, 399) = ( 378 x 399 ) / 7182

= 378 / 399

= 378

Step2:

LCM(21, 855) = 5985

GCD(21, 855) = ( 21 x 855 ) / 5985

= 21 / 855

= 21

Step3:

LCM(3, 843) = 843

GCD(3, 843) = ( 3 x 843 ) / 843

= 3 / 843

= 3

So, Greatest Common Divisor of 378, 399, 855, 843 is 3
