Why would 1 as a prime give many factorizations of a number?
AExtra 1s can be multiplied in
BThe number 1 is an odd number
CThe number 1 is a square number
DThe number 1 is a tiny number
Answer & Solution
Correct answer: A. Extra 1s can be multiplied in
1. If 1 were prime, 6 = 2 x 3 = 1 x 2 x 3 = 1 x 1 x 2 x 3.
2. So each number would have many factorizations with any number of 1s.
3. Being odd, square or small has nothing to do with it.
