Composite Numbers

That's an infinite amount if you don't specify a range.

The numbers 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 are all composite numbers between 1 to 50.

90 has factors other than 1 and itself, so it is not a prime number. For example, 90 is 9 x 10, so it is a composite number.

73 is a Prime number. It is only evenly divisible by itself and one.

A prime number is a number that is divisible only by 1 and itself; it has no other factors. A composite number is a number that is divisible by at least two numbers.

It has more than two factors.

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,

3001 is prime. It is only evenly divisible by itself and one.

Well 63 divided by 3 equals 21.

So 3 times 21 equals 63.

21 is that number.

It has more than two factors.

152, 153, 154

39, since it can be divided by 3 (39/3=13).

All of them except 79 which is a prime number because it has only two factors which are itself and one

The concept of prime number is so important that it has been generalized in different ways in various branches of mathematics. Generally, "prime" indicates minimality or indecomposability, in an appropriate sense. For example, the prime field is the smallest subfield of a field F containing both 0 and 1. It is either Q or the finite field with p elements, whence the name. Often a second, additional meaning is intended by using the word prime, namely that any object can be, essentially uniquely, decomposed into its prime components. For example, in knot theory, a prime knot is a knot which is indecomposable in the sense that it cannot be written as the knot sum of two nontrivial knots. Any knot can be uniquely expressed as a connected sum of prime knots. Prime models and prime 3-manifolds are other examples of this type.

1, 2, 5, 7, 10, 14, 35, 70

no stupid. there is no such thing

1, 2, 3, 4, 6, 12

Both composite.

67 is prime. There's no such thing as a "prime composite number".

36 is the only square number that is also a triangular number between 20 and 40.

The list of non-composite numbers (being shorter) is easier to print. Composite numbers are the ones not on this list:

1009 1013 1019 1021 1031 1033 1039 1049 1051 1061 1063 1069 1087 1091 1093 1097 1103 1109 1117 1123 1129 1151 1153 1163 1171 1181 1187 1193 1201 1213 1217 1223 1229 1231 1237 1249 1259 1277 1279 1283 1289 1291 1297 1301 1303 1307 1319 1321 1327 1361 1367 1373 1381 1399 1409 1423 1427 1429 1433 1439 1447 1451 1453 1459 1471 1481 1483 1487 1489 1493 1499 1511 1523 1531 1543 1549 1553 1559 1567 1571 1579 1583 1597 1601 1607 1609 1613 1619 1621 1627 1637 1657 1663 1667 1669 1693 1697 1699 1709 1721 1723 1733 1741 1747 1753 1759 1777 1783 1787 1789 1801 1811 1823 1831 1847 1861 1867 1871 1873 1877 1879 1889 1901 1907 1913 1931 1933 1949 1951 1973 1979 1987 1993 1997 1999

216 = 2*2*2*3*3*3

They are all the integers from 2 to 200.
