A prime number is a positive integer with two factors: one and the number itself.
No, you can easily see that this is an even number, so it is a multiple of 2.2 IS A PRIME NUMBER!!Any number that is a multiple of a prime number is NOT a prime.
If the tiles cannot be arranged into a rectangle or square it is a prime number.
To identify whether a number is prime or composite, look at its factors. A prime number has exactly two factors: one and itself. A composite number has more factors and can be written as the product of prime numbers. For example: Factors of 17: 1 and 17 so 17 is prime. Factors of 102: 1, 2, 3, 6, 17, 34, 51 and 102 so 102 is composite. It can be expressed as the product of prime numbers by prime factoring: 2 x 3 x 17
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
Identify each number as prime, composite or neither: 1
A prime number is a positive integer with two factors: one and the number itself.
Do you mean, "How can you easily know whether or not a number is prime?"
No, you can easily see that this is an even number, so it is a multiple of 2.2 IS A PRIME NUMBER!!Any number that is a multiple of a prime number is NOT a prime.
Any prime number has only 2 factors which are itself and one
The only arrangement is 1 x 11, identifying the number as prime.
If the tiles cannot be arranged into a rectangle or square it is a prime number.
You can arrange them in one row or column of 11 tiles, identifying the number as prime.
The only possible rectangle is 1 x 11, which identifies 11 as a prime number.

13 and 19 are prime. 33 and 45 are composite.
