An infinite number.

Eight is an even, whole, real, and rational number.

A prime number is any number that only has one and itself as factors. By definition even numbers have a factor of two. Therefore the one even number that is also prime is the number 2.

The question does not make sense. There are not 500 prime numbers but infinitely many!

200 is composite.

Every prime number has exactly 2 factors, 1 and the number itself.

The prime factors of 376 are: 2 and 47. 2 x 47 = 94

2 x 7 x 7

None. 37 is a prime number.

no

As an even number greater than 2, 992 is divisible by 2 and therefore composite. The positive integer factors of 992 are:

1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

No, it is even. The only even prime is 2.

All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.

Example: 210

210 Divide by two.

105,2 Divide by three.

35,3,2 Divide by five.

7,5,3,2 Stop. All the factors are prime.

2 x 3 x 5 x 7 = 210

That's the prime factorization of 210.

no. It can be divisible by 2.

3

Thirty nine is not a prime number because it has more than two factors one and itself and three. To be a prime number it must only have one and itself...

2 and 3

2 and 3 are the only common prime factors

Quite likely that the invention sprang from the desire of several members of the

indiginous population for the ability to count and measure stuff in Korea.

180 = 2 * 2 * 3 * 3 * 5 = 22 * 32 * 5

The only prime factor of 64 is 2.

Yes, those are prime numbers.
