A Carmichael number N is a composite number N with the property that for every b prime to N we have b N−1 ≡ 1 mod N. It follows that a Carmichael number N must be square-free, with at least three prime factors, and that p − 1|N − 1 for every prime p dividing N: ...

Numbers that have factors other than 1 and itself are composite numbers. For example, 15. 15 is divisible by 1, 3, 6 and 15.General Form of Odd NumbersThe general form of odd numbers is given by $2\text{k} + 1$, where $\text{k} \in \text{Z}$ (set of integers)....
The standard form of a rational number can be defined if it’s no common factors aside from one between the dividend and divisor and therefore the divisor is positive. For example, 12/36 is a rational number. But it can be simplified as 1/3; common factors between the divisor and divide...
