Thus, \(p^2-1\) is always divisible by \(6\). fairly sophisticated concepts that can be built on top of Finally, prime numbers have applications in essentially all areas of mathematics. One of these primality tests applies Wilson's theorem. You can't break Main Article: Fundamental Theorem of Arithmetic. When using prime numbers and composite numbers, stick to whole numbers, because if you are factoring out a number like 9, you wouldn't say its prime factorization is 2 x 4.5, you'd say it was 3 x 3, because there is an endless number of decimals you could use to get a whole number. and the other one is one. One can apply divisibility rules to efficiently check some of the smaller prime numbers. m&=p_1^{j_1} \times p_2^{j_2} \times p_3^{j_3} \times \cdots\\ Prime number: Prime number are those which are divisible by itself and 1.
