If the prime factors of a number are all prime numbers less than 10 and no factors repeat what is the number?
The prime numbers less than 10 are 2, 3, 5, and 7. There are several possibilities for the answer to this question since we do not know how many prime factors there are. We know that all of them are less than 10 and they do not repeat. However, we do not know whether the prime factors are all of the the prime numbers less than 10 or a selection of them.
Possibilities:
2 x 3 = 6
2 x 5 = 10
2 x 7 = 14
3 x 5 = 15
3 x 7 = 21
5 x 7 = 35
2 x 3 x 5 = 30
2 x 3 x 7 = 42
2 x 5 x 7 = 70
3 x 5 x 7 = 105
2 x 3 x 5 x 7 = 210

What is the difference between factors of a number and prime factors of a number?
All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.
Do prime numbers have factors?
Yes, prime numbers have factors. A prime number has only two factors(1 and itself).
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.
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.
Which odd numbers are not prime numbers?
A prime number is any number that only has one and itself as factors. Therefore, any number that has more than two factors is not prime. Check the the factors of a number to tell if it is prime or not.
What is the prime numbers for 374?
To find the prime factors of any number then divide the number by prime numbers of increasing value. When a prime number wholly divides the original number repeat the process with the same prime number but each time with the new quotient until complete division does not occur. Repeat with a prime number of higher value until the final quotient is 1. Using this process gives the prime factors of 374 as 2, 11 and 17.
Will you get the same number of factors if you multiply a prime number and itself?
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
What numbers has only 2 factors?
Any prime number, a prime number is a number of which the only factors are it and itself.
What is the difference between factors of a number and prime factors of a number?
All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.
How do you figure out prime numbers not knowing there factors?
But you do know the factors of prime numbers. Every prime number has two factors: one and the number itself.
Do prime numbers have factors?
Yes, prime numbers have factors. A prime number has only two factors(1 and itself).
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 are prime factors numbers?
Prime factors of numbers are small numbers that the bigger (original) number can divide by. The prime factors have to be prime. This means they only have two factors, itself and one.
What numbers has only two factors?
Numbers with only two factors, the number itself and one, are called prime numbers. Examples of prime numbers are 2 (which is the only even prime number) and 17.

Which odd numbers are not prime numbers?
A prime number is any number that only has one and itself as factors. Therefore, any number that has more than two factors is not prime. Check the the factors of a number to tell if it is prime or not.
How are factors and prime numbers related?
Whether a number is a prime number or not is determined by its factors. It is a prime number if its only factors are 1 and itself.
