Given numbers are 381, 603, 277, 855

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

Apply this formula for all numbers.

Step1:

LCM(381, 603) = 76581

GCD(381, 603) = ( 381 x 603 ) / 76581

= 381 / 603

= 381

Step2:

LCM(3, 277) = 831

GCD(3, 277) = ( 3 x 277 ) / 831

= 3 / 277

= 3

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 381, 603, 277, 855 is 1
