first of all take the LCM of 10 12 16 and 18 i.e. 360
now divide 5000 by 360

now subtract 320 from 360
it gives 40
on adding 40 to 5000 we find that it is divisible by all the above mentioned numbers.
hence the answer is 40.

Answer 2

Answer:

FIRST TAKE L.C.M OF 10,12,16 AND 18

THEIR LCM IS 360

WE DIVIDED 360 TO 5000

TO WE GET REMAINDER 320

THEN WE DIVISED 320 TO 360 WE GET 40

TO WE ADD 40 TO 5000 TO WE GET 5040 WE DIVIDED TO 10,12,16 AND 18 TO 5000 DIVIDED BY ALL
