\"I am the number which will make a rectangle 3 times wide\" may mean that
\n" ); document.write( "if the number is the length of a rectangle,
\n" ); document.write( "it will be twice the whole number measurement of the width of that rectangle.
\n" ); document.write( "In other words, I take that to mean that the number is a multiple of \"3\" .
\n" ); document.write( "That means \"3\" is a factor of the mystery number.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"I am the number which has one of my factor as 4\" means that \"4=2%5E2\" is a factor of the mystery number.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"I am the number which is not a multiple of 5 or 7\" tells us that 5 and 7 are not prime factors of that mystery number, but it is not a particularly useful clue.
\n" ); document.write( "Other prime numbers could be factors, like 11, 13, 17, 19, 23, etc .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"I am the number which has exactly 8 factors\" is an important clue.
\n" ); document.write( "A number \"N\" that has \"4=2%5E2\" and \"3\" , but not \"5\" or \"7\" as factors
\n" ); document.write( "has a prime factorization of the form
\n" ); document.write( "\"N=2%5Ea%2A3%5Eb%2A11%5Ec%2A13%5Ed%2A17%5Ee%2A%22...%22\" , with \"a%3E=2\" and \"b%3E=1\".
\n" ); document.write( "The factors of \"N\" , with their prime factorizations, range from
\n" ); document.write( "\"1=2%5E0%2A3%5E0%2A11%5E0%2A13%5E0%2A17%5E0%2A%22...%22\" to \"N=2%5Ea%2A3%5Eb%2A11%5Ec%2A13%5Ed%2A17%5Ee%2A%22...%22\" .
\n" ); document.write( "There are
\n" ); document.write( "\"a%2B1%3E=2%2B1=3\" different possible exponents for \"2\" ,
\n" ); document.write( "\"b%2B1.=1%2B1=2\" different possible exponents for \"3\" ,
\n" ); document.write( "\"c%2B1\" different possible exponents for \"11\" ,
\n" ); document.write( "\"d%2B1\" different possible exponents for \"13\" ,
\n" ); document.write( "and so on.
\n" ); document.write( "With all the combined possible choices, we can make
\n" ); document.write( "\"%28a%2B1%29%2A%28b%2B1%29%2A%28c%2B1%29%2A%28d%2B1%29%2A%28e%2B1%29%2A%22...%22\" factors.
\n" ); document.write( "If \"N\" has exactly \"8=4%2A2\" factors,
\n" ); document.write( "knowing that \"a%2B1%3E=3\" and \"b%2B1%3E=2\" ,
\n" ); document.write( "it is obvious that it must be
\n" ); document.write( "\"a%2B1=4\"<--->\"a=4-1=3\" ,
\n" ); document.write( "\"b%2B1=2\"<--->\"b=2-1=1\" ,
\n" ); document.write( "\"c%2B1=1\"<--->\"c=0\" ,
\n" ); document.write( "\"d%2B1=1\"<--->\"d=0\" ,
\n" ); document.write( "\"e%2B1=1\"<--->\"e=0\" , and so on.
\n" ); document.write( "So, \"N=2%5E3%2A3%5E1%2A11%5E0%2A13%5E0%2A17%5E0%2A%22...%22=2%5E3%2A3=8%2A3=highlight%2824%29\" .
