Composite Numbers

It has more than 1 and itself as factors, so it is a composite number. The factors of 93 are 1, 3, 31 and 93. You can get 93 by 1 x 93 and by 3 x 31.

1 and it is 2

Actually, 71 is not composite it is prime.

15 numbers:

21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39

32+33+34+35+36 (31 is a prime number) = 170

237 is a composite number because it is divisible by 3. 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.

The number 39 is composite because it has more factors than 1 and itself. The factors of 39 are 1, 3, 13, and 39.

when i did this problem i was doing a eratosthenes sieve method and the numbers was from 1-100 so i got the longest string of consecutive composite numbers on the grid are 74-82 this should be right.

BTW I'm 13 doing my moms college work

Sorry, but 79 is a prime number.

I got 90~96

If you can arrange the counters in the shape of a rectangle with at least two in each row and each column then the number is composite. The numbers of row and the numbers of columns are factors of the given number. If the only rectangle you can make is the "degenerate" one, with only one row or only one column, then the number is prime.

1011 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 have a different name.

A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 231 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 2 + 3 + 1 = 6. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 231 is a composite number.

2 divides 48 so it is composite.

Yes.

The composites between 1 and 100 are: 4, 6, 8, 9, 12, 14, 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, 50, 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

The first six composite numbers are: 4, 6, 8 , 9, 10, and 12.

there are infinity odd composite numbers

Composite numbers have factors other than 1 and itself.

So, two good examples are:

62 and 84

A composite number is an integer (usually a positive integer) that can be expressed as the product of smaller integers (other than 1). In other words, a composite number is NOT a prime number, but it has smaller prime numbers as factors.

9 and 15 only.

A prime number is a natural number that has exactly two distinct natural number divisors: 1 and itself.

A composite number is a positive integer which has a positive divisor other than one or itself.

39 is prime, 9 is composite.

The number 2, which is a prime number. Any larger even number is a multiple of 2, and therefore not a prime number.

It is the forth prime number. Whenever you wanted to know a number is prime or composite, use this site. It must be usefull: prime-calculator dot com. It has lots of other abilities. Enjoy it.

It is composite.

250, 252, 253, 254, 255, 256, 258, 259, 260.
