Answer 2

ok sure.

2. 1, 3, 9 ( factors for 27)

4. 1 53

6. 1 71

8. 1, 2, 4 124

10. 1, 12, 2, 144

11. 1,5, 3,


get back to you on the prime and composite :)

Answer 3

2. 27=3*3*3
4. 53=1*53
6. 71=1*71
8. 124=2*2*31
10. 144=2*2*2*2*3*3*
12. 225=3*3*5*5

Tell whether each # is PRIME or COMPOSITE.

14. 3=prime
16. 12=composite
18. 21=composite
20. 33 =composite

Answer 4

27 = 1, 3, 9, 27

53 = Prime 1 and 53

71 = Prime, 1 and 71

124 = 1, 2, 4, 31, 62, 124

144 = 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144

225 = 1, 3, 5, 9, 15, 25, 45, 75, 225

- - - - - - - - - - - - -

3 = Prime

12 = Composite

21 = Composite

33 - Compoiite

Answer 5

02) 27 = (1)(3)(3)(3) --- Factors are 1, 3, 9, and 27.
04) 53 = (1)(53) --- Factors are 1 and 53 (prime number).
06) 71 = (1)(71) --- Factors are 1 and 71 (prime number).
08) 124 = (1)(2)(2)(31) --- Factors are 1, 2, 4, 31, 62, and 124.
10) 144 = (1)(3)(3)(4)(4) --- Factors are 1, 3, 9, 12, 16, 36, 48, and 144.
12) 225 = (1)(3)(3)(5)(5) --- Factors are 1, 3, 5, 9, 15, 25, 45, 75, and 225.

14) 3 ----- PRIME
16) 12 --- COMPOSITE (2 * 2 * 3 = 12)
18) 21 --- COMPOSITE (3 * 7 = 21)
20) 33 --- COMPOSITE (3 * 11 = 33)

Answer 6

27's factors are: 1, 3, 9, 13.5 and 27.
53's factors are: 1, 26.5 and 53.
71's factors are: 1, 35.5 and 71.
124's factors are: 1, 2, 4, 8, 15.5, 31, 62 and 124.
144's factors are: 1, 2, 3, 4, 6, 12, 24, 48, 72 and 144.
225's factors are: 1, 3, 75, 127.5, 5, 45, 37.5, 6, 9, 25, 10, 22.5, 15, 12.5, 18, 50, 4.5 and 225.

3 is a prime number, because nothing else can go into it.
12 is a composite number, because it can be divided by: 1, 2, 3, 4, 6 and 12.
21 is a composite number, because it can be divided by: 1, 3, 7 and 21.
33 is a composite number, because it can be divided by: 1, 3, 11 and 33.
A number which is prime does not allow anything to be multiplied into it, apart from 1 and itself, of course.
A composite number, is on which does allow other numbers to be multiplied into it.

Answer 7

Can you please find ALL the factors of each #?
