What is the smallest number with exactly 14 divisors?
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?
Do you know a quick way to check if a number is a multiple of two?
How about three, four or six?
How shall we start to make some progress with this challenge
Can you generalise your results somehow?
What is the same and what is different
about the solution if the $10$ is changed to another number?
