Full Answer

The number 28 may be presented as a product of 1 and 28, which are two of the factors. It may also be calculated as a product of the following number combinations: 2 and 14, and 4 and 7.

A convenient way to determine the factors of any number is to start with the number 1. The most basic pair of factors of any number is the number 1 and the number itself, since any number multiplied by one is equal to itself. After this, divide the number by two and check if the quotient is a whole number. If it is, include this pair of divisor and quotient as factors of the number. Continue with number 3 and succeeding numbers until the number pairs become as close as possible. All of the whole number pairs generated using this method are the factors of the given number.

  • Q:

    How do you do percentages in math?

    A:

    Percent means “for every 100” or “out of 100.” If 80 percent of the population owns a computer, this implies that 80 out of every 100 people have one. The symbol “%” means percent. Writing a percentage therefore means representing the number out of 100. For instance, finding what percent of 20 is 40: (40/20) * 100 = 200%
