Answer 2

Prime factors of 4,7 and 13

4=2×2

7 and 13 are prime numbers

LCM (4,7,13)=36

we know that, the largest 4 digit number is 9999.

Step 1 : divide 9999 by 364, we get

9999/364

Step 2: subtract 171 from 9999

9999−171=9828

Since a remainder of 3 is to be left

9282+3=9831

Therefore 9831 is the correct answer
