Which of these numbers is a composite number three five seven or nine?
nine
Is five a composite number?
No, five is a prime number because there are only two whole numbers that when multiplied, equals five. (Those numbers are five and one.) In order for a number to be composite, it has to have factors other than itself and one.
What is the prime factorization of a composite number?
A composite number has three or more factors. All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.Example: 210210 Divide by two.105,2 Divide by three.35,3,2 Divide by five.7,5,3,2 Stop. All the factors are prime.2 x 3 x 5 x 7 = 210That's the prime factorization of 210.
Is 2 45 prime or composite?
prime numbers have only factors of themselves and 1; therefore 45 is composite--it has factors of 1,3,5,9,15,45
Which numbers have two three and five as their common factors?
30 and 60
What lowest composite number has the first five prime numbers as factors?
It is 2310.

What is a three digit number that has five consecutive numbers as its factors?
Any three-digit multiple of 60, from 120 to 960, has the first five counting numbers as factors.
How many square numbers are between 1 and 1000 that have five factors?
There are three of them with exactly five factors.
Is 2 45 prime or composite?
prime numbers have only factors of themselves and 1; therefore 45 is composite--it has factors of 1,3,5,9,15,45
What are five prime numbers that have three factors and what are their similarities?
There are no prime numbers with three factors. By definition, a prime number has exactly two factors - 1 and itself.
Prime and composite factors?
A prime number is a whole number that only has two factors which are itself and one. A composite number has factors in addition to one and itself. The numbers 0 and 1 are neither prime nor composite. All even numbers are divisible by two and so all even numbers greater than two are composite numbers. All numbers that end in five are divisible by five. Therefore all numbers that end with five and are greater than five are composite numbers. The prime numbers between 2 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.
If a composite number has the first five prime numbers as factors what is the smallest number it could be?
Just multiply the first five prime numbers! 2x3x5x7x11 = 6x35x11 = 210x11 = 2310. Any multiple of this number "has the first five prime numbers as factors", but 2310 is the smallest such number.
What are five numbers that have three five and seven as prime factors?
105, 210, 315
