LESSON 1 -FACTORS AND MULTIPLES – L.C.M & H.C.F

Objectives:

At the end of the lesson, students should be able to know and list the factors of any given number.

A number that divides exactly into another number without leaving a remainder is a factor of that number.

Note:

Any two numbers that multiply to make a given number are factors of that particular number.

Some numbers may have two factors, i.e. 1 and the number itself. These numbers are referred to as PRIME NUMBERS.

E.g. 3 = {1, 3}                     11 = {1, 11}

       5 = {1, 5}                      23 = {1, 23}
