what has exactly two factors 1 and itself?
538165
A prime number has exactly two factors, 1 and itself. For example, 13 is a prime number because the only factors of 13 are 1 and 13. The number 8 is not prime because it has four factors: 1, 2, 4 and 8. The number 1 is not a prime number because it only has one factor (itself).

1 is a divisible of every number i.e it divides every number. So, 1 is the number which is a factor of every number.

Explanation: A prime number can have only 1 and itself as factors. Any even number has 2 as a factor so if the number has itself , 2 and 1 as factors it can not be prime. 2 is an even number that has only itself and 1 as factors so it is the only even number that is a prime.

Natural numbers that have more than two positive factors are called composite . 1 has only one positive factor i.e. no. 1 only. Hence 1 is neither prime nor composite.

A prime number has only two factors: 1 and itself. A composite number has more than two factors. The number 1 is neither prime nor composite.

The complete list of factors of 52 is: 1, 2, 4, 13, 26, and 52 (all these divide exactly into 52). A prime number has exactly two factors, 1 and itself.

25 has more factors than just 1 and 25 making it composite. The list of factors that it has is 1, 5, and 25. A composite number is a product of prime numbers. So to answer your question.

Since a square root of a number must equal that number when multiplied by itself. When you multiply this number by itself, and set it up as a full equation ( n * n = x ), the two factors (n and n) are either both positive or both negative since they are the same number.

For example, -2 and 3 AND 2 and -3 are both factor pairs of -6. Factors are whole numbers that are multiplied together to produce another number. The original numbers are factors of the product number.

Answer and Explanation: The answer is 1. One is the divisor of every integer. Or, every whole number is the product of 1 and itself.

Yes, every whole number is a multiple of 1. ... Since 1*b = b, for any number b, all numbers are multiples of 1. It sounds like you also want to double-check your understanding of the two words, 'factor' and 'multiple'. If b is a multiple of a, then a is a factor of b.

A factor is a number that divides into another number exactly. To find the common factors of two numbers, you first need to list all the factors of each one and then compare them. If a factor appears in both lists then it is a common factor. For example, the factors of 8 are: 1, 2, 4 and 8.

1 is not prime because it does not have two factors. 2 is prime as it forms a rectangle that is 1 card by 2. So 2 only has two factors.

Factors of 31: 1, 31. Factors of 32: 1, 2, 4, 8, 16, 32. Factors of 33: 1, 3, 11, 33. Factors of 34: 1, 2, 17, 34.

The exponent of prime number 29 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 29 has exactly 2 factors.

2 is not a perfect square. So far, there is no number that is on both lists. Now, look further, if a number is a perfect square, then it must have at least 3 distinct factors, 1, itself and the square root. So for example, 9=3^2 has three factors, 1, 3 and 9.
