| Number Type | Prime Number |
Key fact: 29 is a prime number because its only positive factors are 1 and 29. Its prime factorization is simply 29.
What Are the Factors of 29?
In mathematics, a factor is an integer that divides another number completely without leaving a remainder (a remainder of zero).
What Are the Factors of 29?
When finding what are the factors of 29, test integers starting from 1 up to the square root of 29, which is approximately 5.38.
Final Answer
Since no integer between 2 and 5 divides 29 evenly, the positive factors of 29 are 1 and 29. Therefore, 29 is a prime number.
Factors of 29 = {1, 29}
Factor Pairs of 29
Factor pairs are sets of two numbers that multiply together to equal the original number.
Positive Factor Pairs
The only positive factor pair of 29 is:
Factor pair: (1, 29)
Negative Factor Pairs
Multiplying two negative integers gives a positive integer. Therefore, 29 also has a negative factor pair:
Factor pair: (−1, −29)
Complete Set of Integer Factors
Combining the positive and negative factors, the complete set of integer factors of 29 is:
Remember: 29 is a prime number because its only positive factors are 1 and 29.
Prime Factors of 29 and Prime Factorization
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
- 29 has only two positive divisors: 1 and 29.
- 1 is neither prime nor composite.
- Therefore, 29 is a prime number.

The only prime factor of 29 is 29 itself.
Prime Factorization of 29
Writing a number as a product of its prime factors is called prime factorization. Since 29 is already a prime number, it cannot be broken down into smaller prime factors.
Prime Factorization
29 = 29
The number 29 is itself prime.
A factor tree breaks a composite number into smaller factors until all the factors are prime. Because 29 is already prime, no further breakdown is possible, so a factor tree is unnecessary.
How to Find Factors of 29 by Division Method
How to Find the Factors of 29 Using Division
To systematically verify what are factors of 29, divide 29 by consecutive positive integers. A factor divides 29 exactly, leaving a remainder of zero.
Step 1: Test Consecutive Integers
Divide 29 by the integers starting from 1 and check whether each division leaves a remainder.
| Divisor | Division | Remainder | Result |
|---|---|---|---|
| 1 | 29 ÷ 1 = 29 | 0 | Factor |
| 2 | 29 ÷ 2 = 14 R 1 | 1 | Not a factor |
| 3 | 29 ÷ 3 = 9 R 2 | 2 | Not a factor |
| 4 | 29 ÷ 4 = 7 R 1 | 1 | Not a factor |
| 5 | 29 ÷ 5 = 5 R 4 | 4 | Not a factor |
Only 1 divides 29 exactly among the tested integers. The number 29 itself is also a factor because 29 ÷ 29 = 1.
Step 2: Know When to Stop Testing
You only need to test divisors up to the square root of 29. Once the divisor squared exceeds 29, no new factor pairs can be found.
5² = 25 < 29
6² = 36 > 29
Therefore, √29 is between 5 and 6, so testing divisors beyond 5 is unnecessary.
Step 3: List the Factors
The only positive integer that divides 29 exactly among the tested divisors is 1. Since every number is also divisible by itself, 29 is the other factor.
The positive factors of 29 are:
