I picked the # 13 because that is Taylor Swift's lucky #. My special # is 13 Factors are #s the can be multiplied together to get the original #. Factors of 13 are 1 and 13. Factor pairs are 2 numbers multiplied to get the # you where trying to get. Factor pairs of 13 are 1x13. the # 13 is odd because it can't be divided by 2 equally. An even number can be divided by 2 equally like 6,2,4,12 etc. 13 is not a square # because you can't multiply 2 of the same #s to equal 13. The first 10 multiples of the are 13,26,39,52,65,78,91,195,208,221 a multiple is a 13 multiplyed by a #. Multiples of 13 are 13, 26, 39, 52, 65, 78, 91, 104, 117, 130. Multiples are 13 times a #. A # sentence for 13 is 13x6=78. 1x13

or

13x1 There are no prime factorizations for the # 13 because 13 is already a prime. 3 clues for my speceial number are...

- unlucky

- odd #

- No building has this floor This # is used in real life by the dates the ages and a bakers dozen. THE END
