1.9407 is the largest odd number
2.8876 is the largest even number
3.9861 is the largest multiple of 3
4.2330 is the smallest multiple of 5
5.5124 is the closest number to 5000

This is the answer because you can't alter the numbers without changing whether they are odd or even multiple of 3 or 5 or the closest number to 5000.

Step one: we found an answer.
Step two: we altered them.
Step three: we checked it.
Step four: we compared our answers.
Step five: we swapped the numbers to create larger or smaller answers depending on the requirement.

If you altered them further then you would make the other answers less like their original form.

There may be different solutions but this answer considers all the other numbers.
