Well, the first thing you would need to do is to find the netblocks that are associated with each one.

The first one consists of 8 addresses, which is a /29

61.14.41.136/29 is that netblock

The second one is not truly on a valid netblock boundary, but, I believe apache will still parse it properly. Since it is 64 IPs,

61.14.132.32/26 would match that netblock

61.14.132.128/25 covers that block.

61.14.133.32/28 covers the last block.

Its all CIDR math. So, the simple conversion is to take the size of the block, i.e. 16 IPs, which is 2**4. 32-4 = 28, which is your CIDR subnet.

So, if you take your list, figure out the number of IPs in the range, and determine the CIDR netmask, you can convert it to the CIDR notation, and append it to the starting IP in the block.
