The key to solving this problem is to realize that your mystery number is 2 short of a multiple of 84, 72, and 96. If we call your mystery number \"n\", then \"n%2B2\" is a multiple of 84, 72, and 96.
\n" ); document.write( "\"84=7%2A12=2%5E2%2A3%2A7\"
\n" ); document.write( "\"72=8%2A9=2%5E3%2A3%5E2\"
\n" ); document.write( "\"96=32%2A3=2%5E5%2A3%5E2\"
\n" ); document.write( "The least common multiple of 84, 72, and 96 is
\n" ); document.write( "\"LCM%2884%2C72%2C96%29=2%5E5%2A3%5E3%2A7=96%2A7=672\"
\n" ); document.write( "If the problem just asked for any \"number which when divided by 84, 72 and 96 leaves remainder 82, 70, and 94 respectively,\" we would say that \"n%2B2=672\", with \"n=670\" would be one of many solutions. All the solutions would be numbers such that
\n" ); document.write( "\"n%2B2=672%2Ak\" for some positive integer \"k\".
\n" ); document.write( "As the problem asks for \"the largest 5-digit number,\" we need to look for an \"n%2B2\" multiple of 672 that makes \"n\" the largest 5-digit number complying with the condition.
\n" ); document.write( "\"10%5E5%2F672=about148.8\" according to my calculator, so I can easily estimate that \"n%2B2=148%2A672\" will yield a 5-digit \"n\", while the next larger multiple of 672 \"n%2B2=149%2A672\" will yield a 6-digit \"n\"
\n" ); document.write( "In other words, \"n=148%2A672-2=99454\" is the solution.
