Please provide an integer to calculate its factors, factor pairs, prime factorization, and interactive factor tree.
In number theory, a factor (or divisor) of an integer n is an integer d that divides n completely without leaving a remainder.
For example, 12 can be factored as 1 × 12, 2 × 6, and 3 × 4. Therefore, the positive factors of 12 are 1, 2, 3, 4, 6, and 12.
A prime number is an integer greater than 1 that has exactly two distinct positive divisors: 1 and the number itself.
Examples: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 97...
A composite number is an integer greater than 1 that has more than two positive divisors. It can be factored into smaller positive integers.
Examples: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 120...
A factor tree is a visual branching diagram used to break down any composite integer into its terminal prime factors:
Derived from the exponents of its prime factor decomposition p₁^(e₁) × p₂^(e₂)...
Computes the exact arithmetic sum of all positive integer divisors.
Neither. In modern mathematics, 1 is defined as a unit (the multiplicative identity). Prime numbers must have exactly two distinct positive divisors, whereas 1 only has one (itself).
Factors of non-square numbers always appear in distinct pairs (a × b = n with a ≠ b). For a perfect square, one of the pairs consists of the square root multiplied by itself (k × k = n), resulting in an odd total count of divisors.
A perfect number is a positive integer equal to the sum of its proper divisors (its aliquot sum). For example, 6 has proper divisors 1, 2, and 3, and 1 + 2 + 3 = 6.
