11 is prime, so only 11 and 1
If you can compile a complete list of all different rectangular models with sides of integer length for a number then their lengths and breadths represent its factors.
All of the composite numbers less than 100 have factor pairs.
No, you should continue checking for factor pairs even if you find a pair that repeats. A repeating pair indicates that the number is not a prime number, but there may be other factor pairs that have not been identified yet. It is important to exhaust all possible factor pairs to ensure that all factors of the number are identified accurately.

18. All numbers' highest factor is the number itself.
(54,1)(27,2)(18,3)(9,6)
Factors are numbers you can multiply together to get another number. The factor pairs are: (1, 52) (2, 26) (4, 13)
A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
1 x 101 (101 is a prime number.)
Suppose you have a number n which is not a square. Suppose now that a is a factor of n ie there is some integer b, such that a*b = n. Now since n is not a square, b is not the same as a. Thus for every factor a, there is another factor b ie the factors come in pairs. Therefore, there are an even number of factors.
To ensure that all possible multiplication combinations for a number are found, systematically list all pairs of factors that multiply to that number. For any integer ( n ), check pairs starting from 1 up to ( \sqrt{n} ), as any factor larger than ( \sqrt{n} ) would have a corresponding smaller factor. Additionally, confirm that each pair is unique and ordered to avoid duplicates. This method guarantees that all combinations are accounted for efficiently.
