What numbers would have less than two factors?
Prime numbers
How many numbers are there less than thirty have exactly 6 factors?
Numbers with exactly 6 factors are perfect squares of prime numbers. The prime factorization of a number with exactly 6 factors is in the form ( p^2 ), where ( p ) is a prime number. There are 10 prime numbers less than 30: 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. So, there are 10 numbers less than 30 that have exactly 6 factors.
What are two prime numbers less than 20 whose sum is also a prime number?
2 + 3 = 5
How do you identify prime numbers less than 100?
Numbers can be checked to see if they are primes simply by factoring them. Every prime number has exactly two factors, 1 and the number itself. If there are more or less than 2 factors, the number is not a prime. 1 has only one factor so it is not a prime, and composite numbers have 3 or more factors.
What are 3 numbers less than 50 with 2 factors?
They are: 41, 43 and 47 that have only 2 factors because they are all prime numbers
What is the number whose prime factors are all prime numbers less then 10 and no factor is repeated?
210
All composite numbers less than 100 whose prime factors are 2 and 3?
Yes
What numbers would have less than two factors?
Prime numbers
What are the prime factors of the numbers from 1 to 15000?
The set of prime factors of the numbers from 1 to 15,000 would be the set of prime numbers between 1 and 15,000. The link below has a list of the first 10,000 prime numbers, so if you take the primes less than 15,000, you will have the set of prime factors of the first 15,000 numbers. For prime factors of individual numbers, check the related question, "What are the prime factors of the numbers from 1 to 200?" Also check for WikiAnswers questions in the form of "What are the prime factors of __?" and "What are the factors and prime factors of __?"
What are all the numbers less than 100 with exactly 3 factors that are prime?
By definition, a prime number has exactly two factors. So, there are no prime numbers with exactly three factors.
Give two prime numbers less than 7 whose difference is 2?
5 and 3 are two numbers less than 7, whose difference is 2.
What is the number that is less than 160 has exactly three different prime factors what is the number?
How about 105 whose prime factors are 3, 5 and 7
Three prime numbers all less than 30 whose product is 1955?
Well, well, well, look at you trying to stump me. The prime numbers less than 30 that multiply to 1955 are 5, 13, and 31. Yep, you heard me right, 31 is not less than 30, but it sure is a prime number that gets the job done.
What is special about numbers less than fifty that have less than three factors?
They all are prime numbers except 1
How many numbers are there less than thirty have exactly 6 factors?

There are 10 prime numbers less than 30: 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. So, there are 10 numbers less than 30 that have exactly 6 factors.
What are 2 prime numbers less than 20 whose difference is a prime number?
2 and 5 the difference is 3 which is a prime number
Which numbers are not composite numbers?
Composite numbers have more than two factors. So, the numbers which have two or less than two factors are not composite numbers. Numbers which have exactly two factors are prime numbers. 1 is an exceptional case because it is neither prime nor composite since it has only one factor which is 1.
