Hi, can someone tell me the factors of 2,3,4,5,6,7,8,9,10,11 and 12? sorry, it is a lot!

Sure.
Factors of 2= 1 & 2
Factors of 3= 1 & 3
Factors of 4= 1, 2, and 4
Factors of 5= 1 & 5
Factors of 6= 1, 2, 3, and 6
Factors of 7= 1 & 7
Factors of 8= 1, 2, 4, 8
Factors of 9= 1, 3, 9
Factors of 10= 1, 2, 5, 10
Factors of 11= 1 & 11 
Factors of 12= 1, 2, 3, 4, 6, and 12

Tip: Also, a factor of any number is always 1 and itself, because you can always multiply any number by one to get the same number. 

Hope I helped! :D
