Which number has more than 5 factors?

Table of Factors and Multiples

Do any numbers have 5 factors?

Explanation: Numbers that have a chance of having exactly 5 factors have to be perfect squares (since factors come in pairs, such as with 12: 1, 12; 2, 6; 3, 4) so that they are multiplied by one of their factors twice.

What is another factor of 5?

Prime factorization: 5 is prime. The exponent of prime number 5 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 5 has exactly 2 factors.

Are there any numbers that have 5 factors?

Any number that is p^4 (^ means exponent; p * p * p * p), where p is a prime number, will have five factors. For example, 2 is a prime and 2^4 = 16, which has the 5 factors: 1, 2, 4, 8, 16… Loading… Most numbers have even number factors because the factors come in pairs. For example, the number 12 has 6 factors: 1, 2, 3, 4, 6, 12.

When does a number have an even number of factors?

Most numbers have even number factors because the factors come in pairs. For example, the number 12 has 6 factors: 1, 2, 3, 4, 6, 12. 1 and 12 come in a pair (1 x 12 = 12), 2 and 6 come in a pair, and so on. The only time a number will have an odd number of factors is when the number is a perfect square.

How many factors does a prime number have?

Only prime numbers have exactly two factors. So if a number has exactly five factors then it must be of the form p^4, where p is a prime number. Most numbers have even number factors because the factors come in pairs. For example, the number 12 has 6 factors: 1, 2, 3, 4, 6, 12.
