Can you find a number less than 200 that is divisible by 4 primes?
No. The smallest 4 primes are 2, 3, 5 and 7 and their product is 210.
Composite numbers have more than two of what?
Divisors. Primes are divisible by themselves, and one. Composite numbers also have other divisors.
What is the ninth largest composite number?
There are an infinite number of both primes and composite numbers. There is no largest of either.
Do twin primes have one composite number between them?
No, twin primes are pairs of prime numbers that have only one number between them which is a composite number. For example, (3, 5) and (11, 13) are twin prime pairs with the composite number 4 and 12 respectively between them.
Can you list all the composite numers numbers?
NO because there is an infinite number of them, just like there is an infinite number of primes. In fact, if there is an infinite number of primes there must be an infinite number of composite numbers too... do you see why?
Is there a number from 1 to 100 that is divisible by four different primes?
no the smallest number that is divisible by four different primes would be 210
What is the least positive number that is divisible by three different primes?
30, which is the smallest positive integer divisible by the first three primes: 2, 3 and 5.
What is the smallest integer that cannot occur between two primes?
I'm not sure what you're asking. The smallest number that can't be between two primes is obviously 1. Once you start running into primes, every composite number is between at least two primes.
What is the smallest perfect square that is divisible by the four smallest primes?
44,100
Can you find a number less than 200 that is divisible by 4 primes?

Divisors. Primes are divisible by themselves, and one. Composite numbers also have other divisors.
What numbers are divisible by four prime numbers?
2 * 3 * 5 * 7 = 210 is the smallest one divisible by four unique prime numbers. However, there are an infinite number of them, since there are an infinite number of primes.
What is the smallest composite number that is divisible by 3 5 and 9?
45. Look at the prime decompositions of all three numbers: 3 = 3 5 = 5 9 = 3 * 3 Then take the "union" of all these compositions, i.e. the minimum number of 3s you need is 2, the minimum number of 5s you need is 1 and for all other primes it is 0. Therefore the smallest number divisible by all numbers is 3*3*5 = 45.
What composite number that are prime?
A composite number is basically one that is NOT a prime - a composite number is a product of two or more primes.
Are the multiples of primes composite or prime?
composite seeing as if a number has more factors than 1 and itself.If you multiply a prime number the product will be a composite number. This is because it will have more than two factors as the prime number will be a factor.ExampleThe factors of 3 are:3 : 1,33 multiplied by 3 is 9.The factors of 9 are:9 : 1,3,9Multiples of any numbers other than 1 are composite numbers.The multiples of primes are composite, because they are divisible by the two numbers that were multiplied to make it.
What is the name of the product that has more than one factor?
A composite number. Actually, all integers have at least two factors. Even primes are divisible by 1 and themselves.
What is the ninth largest composite number?
There are an infinite number of both primes and composite numbers. There is no largest of either.
