It is 11*13 = 143
No. The smallest 4 primes are 2, 3, 5 and 7 and their product is 210.
Divisors. Primes are divisible by themselves, and one. Composite numbers also have other divisors.
There are an infinite number of both primes and composite numbers. There is no largest of either.
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.
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?
no the smallest number that is divisible by four different primes would be 210
30, which is the smallest positive integer divisible by the first three primes: 2, 3 and 5.
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.

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.
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.
A composite number is basically one that is NOT a prime - a composite number is a product of two or more primes.
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.
A composite number. Actually, all integers have at least two factors. Even primes are divisible by 1 and themselves.
There are an infinite number of both primes and composite numbers. There is no largest of either.
