What you are looking for is supernetting/CIDR (Classless inter domain routing). Instead of splitting a network into smaller parts, you group every adjacent network together.

What you do, to achieve this is convert every network address in binary, and compare up to which digit every network address matches. convert those bits back to decimal and you have your supernet.

(Or use an online calculator like http://www.subnet-calculator.com/cidr.php)
