Definition of Factor <\/h2>\n\n\n\n

When a given number can be divided by another number, including itself, without any remainder, it is called a factor of the given number.<\/p>\n\n\n\n

Let’s explain factors through an example:<\/p>\n\n\n\n

Suppose there is a number 6 and we have to find out its factor<\/p>\n\n\n\n

Condition for factor<\/strong>: Numbers that can divide the number 6 without leaving a remainder.<\/p>\n\n\n\n

    \n
  1. 6\/1 = 6 (6 is divided by number 1 without leaving remainder; therefore, number 1 is called factor of 6.)<\/li>\n\n\n\n
  2. 6\/2 = 3 (6 is divided by number 2 without leaving remainder; therefore, number 2 is called factor of 6.)<\/li>\n\n\n\n
  3. 6\/3 = 2 (6 is divided by number 3 without leaving remainder; therefore, number 3 is called factor of 6.)<\/li>\n\n\n\n
  4. 6\/4= 1.5 (6 is divided by number 4 with remainder; therefore, number 4 is not a factor of 6)<\/li>\n\n\n\n
  5. 6\/5 = 1.2 (6 is divided by number 5 with remainder; therefore, number 5 is not a factor of 6)<\/li>\n\n\n\n
  6. 6\/6 = 1 (6 is divided by number 6 without leaving remainder; therefore, number 6 is called factor of 6.)<\/li>\n<\/ol>\n\n\n\n

    Based on the information above, Number 6 can be divided evenly by 1, 2, 3, and 6 . Therefore,<\/p>\n\n\n\n

    Factor of Number 6 = ( 1, 2, 3, 6)<\/p>\n\n\n\n

    Let’s take another example: Find the factors of number 24<\/p>\n\n\n\n

    Condition for factor<\/strong> : Numbers that can divide the number 24 without leaving a remainder.<\/p>\n\n\n\n

    The number 24 can be fully divided by 1, 2, 3, 4, 6, 8, 12, and 24.<\/p>\n\n\n\n

    Therefore, Factors of Number 24 = ( 1, 2, 3, 4, 6, 8, 12, 24 )<\/p>\n\n\n\n

    Greatest or Highest Factor<\/h2>\n\n\n\n

    From the above two examples, we can conclude that the greatest factor of a number is the number itself.<\/p>\n\n\n\n

    Least Factor <\/h2>\n\n\n\n

    A “least factor” is the lowest positive integer that divides a given number without leaving a remainder . Since 1 is the smallest positive integer<\/a> and a factor of all positive integers, it is always the least factor.<\/p>\n\n\n\n

    Prime Factor<\/h2>\n\n\n\n

    Every number is divisible by 1 and itself. Therefore, we can say that each number has at least two factors: 1 and the number itself. When a number has only these two factors, it is called a Prime Factor. Prime factors are factors that are prime numbers<\/a>.<\/p>\n\n\n\n

    Composite Factor<\/h2>\n\n\n\n

    A number that has more than two factors is called a composite number.<\/p>\n\n\n\n

    Factor Pair<\/h2>\n\n\n\n

    Factors come in pairs. If ‘a’ is a factor of ‘b,’ then ‘b\/a’ is also a factor of ‘b.’ For example, if 2 is a factor of 12, then 6 is also a factor of 12.<\/p>\n\n\n\n

    Important Facts about Factors<\/h2>\n\n\n\n

    Factors of any number are finite.<\/p>\n\n\n\n
