I have a file with many lines

```
http://example.com/part-1   this    number 1 one 
http://example.com/part--2  this is number 21 two
http://example.com/part10   this is an number 12 ten
http://example.com/part-num-11  this is an axample  number 212 eleven

```

How can I remove all character after "number x" + between first columd and "number x"...I wanna my output like this

```
http://example.com/part-1    1
http://example.com/part--2   21 
http://example.com/part10    12
http://example.com/part-num-11   212 

```

Another case : 
Input: 

```
http://server1.example.com/00/part-1    this    number 1 one 
http://server2.example.com/1a/part--2   this is section 21 two two
http://server3.example.com/2014/5/part10    this is an Part 12 ten  ten ten
http://server5.example.com/2014/7/part-num-11   this is an PARt number 212 eleven

```

I wanna the same output....And the number is always in last numeric field
