Answer 2

Answer:

prime factorisation of 4,7,13.

4=(2×2)

7=(7×1)

13=(13×1)

lcm=product of greatest power of each prime factor .

2×2×7×13=364

Greatest number is 9999.

Then we divide 9999÷364 leaving remainder 171.

required number =(9999-171)=9828+3=9831

THE GREATEST NUMBER WHICH DIVIDES 4,7,12 IS 9831, respectively..
