The sum of its factors (including one and itself) sum to 360, exactly three times 120. Perfect numbers are order two ( 2-perfect ) by the same definition. 120 is the sum of a twin prime pair (59 + 61) and the sum of four consecutive prime numbers (23 + 29 + 31 + 37), four consecutive powers of two (8 + 16 + 32 + 64), and four consecutive powers ...
When such a divisor is found, the repeated application of this algorithm to the factors q and n / q gives eventually the complete factorization of n. [1] For finding a divisor q of n, if any, it suffices to test all values of q such that 1 < q and q 2 ≤ n. In fact, if r is a divisor of n such that r 2 > n, then q = n / r is a divisor of n ...

Continuing this process until every factor is prime is called prime factorization; the result is always unique up to the order of the factors by the prime factorization theorem. To factorize a small integer n using mental or pen-and-paper arithmetic, the simplest method is trial division : checking if the number is divisible by prime numbers 2 ...

In mathematics, the fundamental theorem of arithmetic, also called the unique factorization theorem and prime factorization theorem, states that every integer greater than 1 can be represented uniquely as a product of prime numbers, up to the order of the factors. [3] [4] [5] For example,
Grades 2 through 8 tests cover mathematics and English/language arts (which includes writing in grades 4 and 7). Grades 9 through 11 cover English/language arts, mathematics, and science. History-social science tests are added for grades 8, 10 and 11 as well as science for grades 5 and 8. Except for writing, all questions are multiple-choice.
