Prime Numbers
In this section let me help you on list of primes. If a number does not have a factor beside 1 and itself, it is called prime.
Example :5 has no factor, whole numbers that can be divided by evenly, besides 1 and 5. It is therefore prime.20, and the other hand, the factors 1, 2, 4, 5, 10 and 20. Because it has factors beside 1 and itself (2, 4, 5 and 10), it is not prime.
Numbers that are not prime is called composite. 20 is a composite number.
Examples of prime numbers are 2, 3, 5, 7, 11 and 13.
Prime Factor:
The Factors are number you multiply to get other number. For instance , the factor of 15 are 5 and 3, because 5×3 = 15. Some numbers are more than one factors (more than one way of being factorization).This could also help us on date calculator number of days. For instance , 12 can be factored as the 1×12, 2×6, or 3×4. The number that can only be factors as 1 times itself is called prime. The few primes numbers are 2, 3, 5, 7, 11, and 13. The number 1 is not regards as to a prime, and is usually not included in factorizations.
