Answer:
a) 9, 18, 27, 36, 45 b) 1, 2, 4, 8, 16, 32 c) 2, 3, 5, 7, 11
Explanation:
a) To find the first five factors, you just need to multiply nine by 1, 2, 3, 4, and 5 and there are your answers :)
b) 1x32=32, 2x16=32, and 4x8=32, but none other whole numbers can multiply to get 32. So those are the factors of 32.
c) Prime numbers are ones who's only factors are 1 and themselves. 2, 3, 5, 7, and 11 are the first of the list because you will not find any other factors.
