\n<\/strong>
\n\u00a0COMMON MULTIPLES AND FACTOR
\n<\/strong>Factors:<\/strong> The factor of a number is the whole number that divides the number exactly. For example the factors of 18 may be found as follows;
\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a018 = 1 x 18
\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 = 2 x 9
\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 = 3 x 6
\nMultiples:<\/strong> A multiple of a number is obtained by multiplying it by any whole number. Example the multiple of 4 are 4, 8, 12, 16, 20 , 24 etc.
\nA prime number is a number that can only divide itself. It has only two factor which is 1 and itself. Examples of prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19 etc.
\nExample: <\/strong>(a) find all the factors of 18
\n\u00a0\u00a0\u00a0\u00a0(b) State which of these factors are even
\n\u00a0\u00a0\u00a0\u00a0( c) state which of these factors are prime numbers
\n\u00a0\u00a0\u00a0\u00a0(d) Write the first three multiple of 18
\nSolution
\n<\/strong><\/p>\n

    \n
  1. \n
    Factors of 18 are 1, 2, 3, 6, 9, and 18\n<\/div>\n<\/li>\n
  2. \n
    The even numbers are 2, 6, and 18\n<\/div>\n<\/li>\n
  3. \n
    The prime numbers are 2 and 3\n<\/div>\n<\/li>\n<\/ol>\n

    Example 1:<\/strong> Find the factor of 56
    \nSolution:
    \n<\/strong>1 \u00d7 56
    \n2 \u00d7 28
    \n4 \u00d7 14
    \n7 \u00d7 8
    \nTherefore 56
    \n\t\t\t<\/strong>= 1, 2, 4, 7, 8, 14, 28, and 56.
    \nProduct of Prime Factors.
    \n<\/strong>Example 2:<\/strong> Express 56 and 108 as the product of prime factors in index notation.
    \nSolution:<\/strong>
    \n\t\t56 = 2 \u00d7 2 \u00d7 2 \u00d7 7 = 23<\/sup> x 7
    \n108 = 2 \u00d7 2 \u00d7 3 \u00d7 3 \u00d7 3 = 22<\/sup> x 33<\/sup>
    \n\t\tNote that the numbers must be a prime numbers
