Factors of 139

The numbers that divide 139 evenly are known as factors of 139. A factor of 139 is a number that divides the number without a remainder. The factors of 139 are 1 and 139.

Negative factors of 139: -1 and -139.

Prime factors of 139: 139. Since 139 is a prime number, it has no prime factorization other than itself.

The sum of factors of 139: 1 + 139 = 140

Factors can be found using different methods. Mentioned below are some commonly used methods:

1. Finding factors using multiplication
2. Finding factors using division method
3. Prime factors and Prime factorization

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 139. Identifying the numbers which are multiplied to get the number 139 is the multiplication method. Since 139 is a prime number, the only multiplication that gives 139 is:

Step 1: Multiply 139 by 1, 139 × 1 = 139.

Therefore, the positive factor pair of 139 is: (1, 139). For every positive factor, there is a negative factor.

Dividing the given number with whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 139 by 1, 139 ÷ 1 = 139.

Step 2: Check if 139 can be divided by any other whole number except 139 itself, which it cannot since it is a prime number.

Therefore, the factors of 139 are: 1 and 139.

The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:

• Using prime factorization
• Using factor tree

Using Prime Factorization: In this process, since 139 is a prime number, it cannot be broken down further into other prime factors. The prime factorization of 139 is simply 139.

The factor tree is the graphical representation of breaking down any number into prime factors. However, since 139 is a prime number, it does not break further. So, the prime factorization of 139 is just 139.

Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.

• Positive factor pair of 139: (1, 139).
• Negative factor pair of 139: (-1, -139).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 139 are 1 and 139.

• Prime factors: The factors which are prime numbers. Since 139 is a prime number, it is its own prime factor.

• Factor pairs: Two numbers in a pair that are multiplied to give the original number are called factor pairs. For example, the factor pair of 139 is (1, 139).

• Prime number: A number greater than 1 with no divisors other than 1 and itself. 139 is an example of a prime number.

• Multiplication method: A method to find factors by identifying number pairs that produce the target number. For example, 1×139 gives 139.
