The numbers 3,5,qnd 7 are prime numbers.
\n" ); document.write( "If a number is a multiple of 3, 5, and 7,
\n" ); document.write( "each of those prime numbers appears at least once in the prime factorization of the number.
\n" ); document.write( "The number is going to be $\"3%2A5%2A7%2Asomething\"$ .
\n" ); document.write( "In other words, it must be a multiple of $\"3%2A5%2A7=105\"$ .
\n" ); document.write( " $\"5000%2F105=47.6\"$ (rounded),
\n" ); document.write( "so the numbers you are looking for are
\n" ); document.write( " $\"1%2A105=105\"$
\n" ); document.write( " $\"2%2A105=210\"$
\n" ); document.write( " $\"3%2A105=315\"$
\n" ); document.write( " and so on, all the way up to
\n" ); document.write( " $\"47%2A105=4935\"$ .
\n" ); document.write( "There are obviously $\"highlight%2847%29\"$ common multiples of 3, 5 and 7 between 1 and 5000. \n" ); document.write( "

\n" );
