What whole number less than 100 have exactly 3 factors?
The square of any prime number has exactly three factors: 22, 32, 52, etc.
What is a number less than 160 and has exactly 3 different prime factors?
How about 30 or 105
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 3 numbers less than 50 have exactly 2 factors?
Every prime number has exactly two factors. They are '1' and the number itself. There are 15 prime numbers less than 50. A few of them are 2, 3, 5, 7, 11, 13, and 47.
What is special about number that are less than 50 and exactly 3 factors?
Nothing special. They are squares of prime numbers.
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.
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
What odd number is less than 40 and has exactly three prime factors?
27

Nothing special. They are squares of prime numbers.
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 number is an odd number that is less than 160 that has exactly 3 different prime factors?
105 and the primes are 3, 5, and 7
