Factors and Multiples

Factors

A factor of a number is defined as the number that divides the given number exactly without any remainder.

Examples:

Boy

We know that 8 is divisible by 4 completely without any remainder. Therefore, 4 is the factor of 8.

Alternatively, the factor of a number is defined as two numbers such that the product of numbers is equal to the given number.

Examples:

Boy

The product of the numbers 3 and 2 is equal to 6. Therefore, 2 and 3 are the factors of 6.

A number may have many factors.

Properties of Factors

  • A number may have many factors.
  • Every number is a factor of itself.
  • 1 is the factor of every number.
  • Every number other than 1 has at least two factors, i.e., 1 and itself.

Multiples

The multiples of the number are the product of the numbers with the natural numbers.

Examples:

The first ten multiples of the number 12 are:

12 × 6 = 72

12 × 7 = 84

12 × 8 = 96

12 × 9 = 108

12 × 10 = 120
