Uhm… Are we supposed to do all of the divisions up to half the number to find out?

Seems like it takes too much time during the test

No, you never really have to check outside of 2, 3, 7, 9 and occasionally 11 when the numbers are close to 100

For example 113/2 = 56.5, if there is a number around 56.5 when multiplied with x, that gives 113, then it can either be 2 or 3

As you have already checked for 2 and 3

You don’t need to search that number

I hope this makes sense
