15 is a composite number because it has more than two factors. Its factors are 1, 3, 5, and 15.
15 is a composite number as it is divisible by 1, 3, 5 and 15.
composite. 3*5=15
15 is a composite number because it has more than 2 factors

The largest composite number between 1 and 50 is 50.

Here they are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100

4=2*2

6=2*3

8=2*2*2

9=3*3

10=2*5

12=2*2*3

14=2*7

15=3*5

16=2*2*2*2

18=2*3*3

You would write it like this 480,000,000.

4,6,8,9,10,12,14,15

No it is a prime number

58

All even numbers greater than 2 are composite because they are divisible by 2 and thus have at least three factors. The number 2, itself, is a prime number because it has only two factors: 1 and itself.

There are 7 composite numbers from 10 to 20 (including the boundaries):
10, 12, 14, 15, 16, 18 and 20

1 million in standard form would be 1,000,000 = 1 x10^6
1,000,000

Greater than one, numbers are either composite or prime, never both.

There are not any numbers that are both prime and composite. A prime number has exactly two factors. A composite number has more than two factors.

The factors of 11111 are 1, 41, 271, 11111, which makes it composite.

You would write it like this 5,500,000.

18 = 2 * 3 * 3

4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30,32,33,34,35,36,38,39,40,42,44,45,46,48, and 49

4 6 8 9 10 12 14 15 16 18 20 21 22 24 26 25 27 28 30 32 33 34 35 36 38 39 40 42 44 45 46 48 49 50 51 52 54 55 56 57 58 60 62 63 64 65 66 68 69 70 72 74 75 76 77 78 80 81 82 84 85 86 87 88 90 91 92 93 94 95 96 98 99 100

Oh, dude, you want the odd composite numbers less than 20? Alright, let me break it down for you. So, we've got 9, 15, and 21. Wait, no, scratch that last one, it's above 20. But yeah, those are the odd composite numbers you're looking for. Like, you're welcome.

Neither.

120 and 49

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1, 2, and 0. 1, 2, and 0 have a different name.

39 is composite.

Yes(: it can be divided by four and two....

Your Welcome<3

No 28 is a composite number

and not a multiple of 3
