I know that 12 times 12 is 144 so if I go 1 digit higher I would do 13 times 13 which is 169. 169 is in between 150 and 180.
4 x 9 = 36 So 9 goes into 42 = 4 times with a remainder of 6

13 is a prime number so only 13 and one can go into it
221 ÷ 13 = 17.
1, 13, 17, 221.
17 with 4 remainder 225 - 4 = 221 = 13 x 17
1, 13, 17 and 221.
