               SUBTOPIC: Factors and Multiples


                     Factors:A factor of a number is an exact divisor of that number.
                       Ex- Factors of the number 4 are as following:
                       1 x 4 = 4;  2 x 2 = 4;  4 x 1 = 4. This shows that 1, 2 and 4 are factors of 4.
                     Facts about factors:
                          1.  1 is a factor of every number.
                          2.  Every number is a factor of itself.
                          3.  Every factor of a number is an exact divisor of that number.
                                4. Every factor is less than or equal to the given number.

                     Multiples: A multiple of a number is defined as a number which is a product
                       of that number and any other whole number.
                       Ex- https://www.examfear.com/notes/Class-6/Maths/Playing-With-
                       Numbers/1660/Multiples.htm

                     Common Factors: When two (or more) numbers have the same factor, that
                       factor is known as a common factor.
                           Ex- Let’s find common factors of 12 and 16.
                       Factors of 12 are 1, 2, 3, 4, 6 and 12.
                       Factors of 16 are 1, 2, 4, 8 and 16.
                       Clearly, 1, 2 and 4 are the common factors of 12, and 16

                     Common Multiples: A common multiple is number that is a multiple of two or
                       more numbers.
                            Ex- The common multiples of 3 and 4 are 0, 12, 24 ….
