### 14 Divisors

What is the smallest number with exactly 14 divisors?

### Summing Consecutive Numbers

Many numbers can be expressed as the sum of two or more consecutive integers. For example, 15=7+8 and 10=1+2+3+4. Can you say which numbers can be expressed in this way?

### Dozens

Do you know a quick way to check if a number is a multiple of two? How about three, four or six?

# Weekly Problem 42 - 2010

##### Stage: 3 Short Challenge Level:

If we rewrite the equation we get the product $E\times I\times G \times H\times T = T\times W \times O\times F\times O \times U \times R$.

There are $10$ different letters here, so each number from $0$ to $9$ must be represented by one of the letters. So one letter is $0$. Any product where this letter appears is $0$. Hence both sides must include this letter. The only letter on both sides is $T$.

Hence $T=0$ and the product $T\times H\times R \times E \times E =0$.

This problem is taken from the UKMT Mathematical Challenges.
