What are the prime numbers between 60 and 70?\r
\n" ); document.write( "\n" ); document.write( "All even numbers are not prime
\n" ); document.write( "That leaves 61, 63, 65, 67, 69 to investigate
\n" ); document.write( "65 ends in 5, so it is divisible by 5
\n" ); document.write( "63, 66 and 69 have digits that all sum to a number divisible by 3 (9,12 and 15). so they are not prime
\n" ); document.write( "That leaves 61 and 67. They are not divisible by 7 or 11. They are prime
\n" ); document.write( "So how many composite numbers, inclusive
\n" ); document.write( "60, 62, 63, 64, 65, 66, 68, 69, 70
\n" ); document.write( "Nine total\r
