Given numbers are 855, 361, 981, 250

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

Apply this formula for all numbers.

Step1:

LCM(855, 361) = 16245

GCD(855, 361) = ( 855 x 361 ) / 16245

= 855 / 361

= 855

Step2:

LCM(19, 981) = 18639

GCD(19, 981) = ( 19 x 981 ) / 18639

= 19 / 981

= 19

Step3:

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

= 1 / 250

= 1

So, Greatest Common Divisor of 855, 361, 981, 250 is 1
