Every even number but 2. Even numbers have 2 as a factor (by definition), so higher even numbers can be separated into two factors, 2 and some other number. For example, 6 = 2 x 3.

Prime numbers have only two factors: one and themselves. By definition, your product would have more than that: one, the product and at least the two numbers that created the product. It has to be composite.

No because every single number has a factor of one, therefore you have one as the common factor.

The only number with a single factor is ' 1 '. Every other number has at least two factors: ' 1 ' and itself. A number with only those two factors and no others is called a "prime" number.

It is a negative number, because every pair of negative factors makes a positive, and you have 10 pairs plus one left over.

' 1 ' and itself.

At least two factors because prime numbers have two factors and composite numbers have more than two factors.

Every positive integer greater than 1 can be expressed as the product of a unique set of prime factors. The count of these factors is the prime factors number for the number.

No, square numbers have an odd number of factors.

All the numbers up to 100 are factors in some numbers up to 100. For example, 1 is a factor of every number and 2 is a factor of all the even numbers. The numbers greater than 50 are only factors of themselves among the numbers up to 100, 95 is only a factor of itself, because the next number for which it is a factor is 190, which is greater than 100.

No. They have different number of factors

But you do know the factors of prime numbers. Every prime number has two factors: one and the number itself.

The concept of factors makes sense in the context of whole numbers. In the context of other numbers, every number is divisible by every non-zero number.

There are an infinite amount of numbers greater than two that are composite numbers. Every even number, for instance, is a composite number

one (1) and the number itself

Every number greater than 1 has 1 and the number itself as factors. If it has no other factors besides these two factors, it is a prime number. If it has more factors than 1 and itself, it is a composite number.

Every product of two prime numbers has four factors.
