List the numbers out from 62 to 72
\n" ); document.write( "{62,63,64,65,66,67,68,69,70,71,72}
\n" ); document.write( "It needs to be a composite # so take those primes out!
\n" ); document.write( "{62,63,64,65,66,68,69,70,72}
\n" ); document.write( "Now find a prime in the sum of the numbers
\n" ); document.write( "6+2=8 NOPE
\n" ); document.write( "6+3=9 NOPE
\n" ); document.write( "6+4=10 NOPE
\n" ); document.write( "6+5=11 YEP!
\n" ); document.write( "6+6=12 NOPE
\n" ); document.write( "6+8=14 NOPE
\n" ); document.write( "6+9=15 NOPE
\n" ); document.write( "7+0=7 YEP!
\n" ); document.write( "7+2=9 NOPE\r
\n" ); document.write( "\n" ); document.write( "So now down to the last two numbers
\n" ); document.write( "{65&70}
\n" ); document.write( "finally find the # with MORE than 4 factors. Very key to see that it wants more than four. \r
\n" ); document.write( "\n" ); document.write( "65-> 1, 5, 13, 65 This has only four so it can't be it since we need more than four.\r
\n" ); document.write( "\n" ); document.write( "70-> 1, 2, 5, 7, 10, 14, 35, 70 This has WAY more than four for sure, it has eight so this by default and with reason is the right answer. \r
\n" ); document.write( "\n" ); document.write( "Answer: 70\r
\n" ); document.write( "\n" ); document.write( "Make sure to go through the whole thing sometimes even the smallest mistake can get the best of us. Hope this helped
