If p is the greatest prime factor of 34 and q is the greatest prime factor of 90, what is the greatest prime factor of the product pq ?\r

document.write( "\r\n" );
document.write( "Here's a list of the first dozen prime numbers.\r\n" );
document.write( "\r\n" );
document.write( "2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37.\r\n" );

\r\n" );
document.write( "The largest number in that list of prime numbers \r\n" );
document.write( "that will divide evenly into 34 is 17.\r\n" );
document.write( "\r\n" );
document.write( "So p is 17.\r\n" );

document.write( "The largest number in that list that will divide \r\n" );
document.write( "evenly into 90 is 5.\r\n" );
document.write( "\r\n" );
document.write( "So q is 5.\r\n" );
document.write( "

\n" ); document.write( ">>...what is the greatest prime factor of the product pq?...<<

\r\n" );
document.write( "Since pq is 17x5 or 85, and there are only two prime factors of it,\r\n" );
document.write( "17 and 5, obviously the larger one is 17.\r\n" );
