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.
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 is the largest number less than 500 that is the product of exactly two prime numbers?
345
What is an odd number less that 160 that has exactly 3 prime numbers?
5+19+79 = 103
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 a prime number'?
A prime number is a number that has exactly two factors: 1 and itself. All whole numbers greater than 1 are either prime numbers or can be written as the product of prime numbers. There are an infinite number of prime numbers, but they occur less frequently among larger numbers. Prime numbers are important in cryptography and number theory.Read more: http://wiki.answers.com/Q/FAQ/7008#ixzz1LVq5EURw
What is special about number that are less than 50 and exactly 3 factors?
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 is the total number of prime numbers less than 100?
The total number of prime numbers less than 100 is 25.
What are all the numbers less than 100 that are the product of exactly three different prime numbers?
All the numbers less than 100 that are the product of exactly three different prime numbers are 30, 42, 66, 70, and 78.
What are all of the numbers less than 100 that are the products of exactly three different prime numbers?
All the numbers less than 100 that are the product of exactly three different prime numbers are 30, 42, 66, 70, and 78.
What are numbers less than 100 that are the product of exactly 3 different prime numbers?
All the numbers less than 100 that are the product of exactly three different prime numbers are 30, 42, 66, 70, and 78. Need to know how to get the answer
