The first 10 multiples of 43 are 43, 86, 129, 172, 215, 258, 301, 344, 387, 430. I chose 43 because 4 is my second lucky number and 3 is the second number in my favorite and first lucky number; 13. My Special Number BY NICK COCHRAN The factors of 43 are 43 and 1. 43 is a prime number because the only numbers that go into it are 43 and 1 . There is one factor pair and it is 1 and 43. 43 is an odd number because if you divided it by 2 you would have a remainder. 43 is not a square number because there is no number that you can multiply by itself to equal 43. 43*1=43 , 1 is a multiple of 43 because 43*1=43 A riddle for my number is: This number is a two digit multiple of 86, it is a prime number, the only other number that goes into it is 1 and the sum of the two digits in this number equals 7.
