Before giving you the factors of 28, here is a small introduction:

The factors of a number are the numbers that divide that number exactly.

For example, the product 2 × 3 comprises two factors 2 and 3, or 3 × 7 × 12 7 admits as a factor.

“To factors”, “broken down into factors” or “factoring” a number or algebraic expression, is in search of the factors, if they exist: it is generally considered that some say trivial factorization, as 19 = 1 × 19 or x2 – 1 = (-1) × (1 – x2), “do not count”, which is why we say that, by definition, a prime number can not be factored, since it acts as only divisors 1 and itself.

A major problem, subject of much research in both mathematics and algorithms is the decomposition of a number into prime factors; this problem has particularly applications in cryptography.

More generally, given a1, a2, …, an, a, the relationship a × a × a1 + a2 + … + a × a × an = (a1 + a2 + … + year) makes it possible to factor in. a is called “common factor”.
