Why is 35 a prime number?
It is not a prime number, since it has smaller factors.
Why are no prime number a perfect number?
The only factors of a prime are 1 and itself. So, the only factor smaller than the number itself is 1. Therefore the sum of all factors smaller than the number is 1. But 1 is not a prime number. Thus, there is no prime number that is a perfect number.
Are there prime numbers that are also square mumbers?
No. That isn't possible: A prime number, by definition, has no smaller factors. A square number does have a smaller factor - the number that is squared.
How is a prime number different from the factors?
A prime number has only two factors, one and the number itself. A composite number has more than two factors. Factors can be either prime or composite.
How is prime factorization different from finding factors of a number?
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. When finding the factors of a number, you find all the factors. The prime factorization is a multiplication string of just prime factors that will total the given number.
How do you calculate first ten prime numbers?
You go through each number, starting with 2, 3, 4, ... and check if the number has any smaller factors. If it has no smaller factors, you conclude it is a prime number. Continue until you have 10 prime numbers.
What number has five different prime factors?
Since there are an infinite number of prime numbers, there are infinite numbers with any given number of prime factors.
What is 3 prime and 5 prime?
3 and 5 are prime numbers. This means they can't be separated into smaller factors. For comparison, 9 is not a prime number, since it CAN be separated into smaller factors (9 = 3 x 3).
What is the least number that has 4 different prime factors?
Logically, the smallest number with 4 different prime factors would have to be the product of the smallest four prime numbers. So the smallest natural number with four different prime factors is 210 (2*3*5*7).
Do large numbers have more prime factors than smaller numbers?
Usually, but not necessarily and not if they're prime. All prime numbers have the same number of factors.
What is a number that is not a prime number?
Then it is called a "composite number". A composite number has smaller prime numbers as its factors; for example, 6 = 2 x 3.
How is a composite number different from a prime number?
A composite number has more than two factors whereas a prime number has only two factors
