Factors of 182

The factors of 182 are the numbers that divide 182 evenly without leaving a remainder value. The factors and the pair factors of 182 can be represented in both positive and negative forms. For example, the factors of 182 can be represented as (1, 182) or (-1, -182). We know that the multiplication of two negative numbers results in a positive number. Hence, if we multiply -1 and -182, it will result in the original number 182.

In this article, we are going to learn the factors of 182, the positive and negative factors of 182, how to find the prime factors of 182 using the prime factorization method and many solved examples.

What are the Factors of 182?

The numbers that divide 182 completely and leave a remainder 0 are the factors of 182. In other words, the numbers that are multiplied together in pairs resulting in the number 182 are the factors of 182. As the number 182 is an even composite number, it has many factors other than 1 and 182. Therefore, the factors of 182 are 1, 2, 7, 13, 14, 26, 91 and 182. Similarly, the negative factors of 182 are -1, -2, -7, -13, -14, -26, -91 and -182.

Pair Factors of 182

The pair factors of 182 are the pair of numbers, in which the two numbers in the pair are multiplied together resulting in the original number 182. Since 182 is a composite number, it has more than one pair factor. Thus, the positive and negative pair factors of 182 are given below:

Positive Pair Factors of 182:

Therefore, the positive pair factors of 182 are (1, 182), (2, 91), (7, 26) and (13, 14).

Negative Pair Factors of 182:

Hence, the negative pair factors of 182 are (-1, -182), (-2, -91), (-7, -26) and (-13, -14)

Factors of 182 by Division Method

In the division method, the factors of 182 are found by dividing the number 182 by different integer numbers. If the integer divides 182 completely without leaving any remainder, then the integer is a factor of 182. Now, let us start dividing 182 by 1 and then proceed with the different numbers.

• 182/1 = 182 (Factor is 1 and Remainder is 0)
• 182/2 = 91 (Factor is 2 and Remainder is 0)
• 182/7 = 26 (Factor is 7 and Remainder is 0)
• 182/13 = 14 (Factor is 13 and Remainder is 0)
• 182/14 = 13 (Factor is 14 and Remainder is 0)
• 182/26 = 7 (Factor is 26 and Remainder is 0)
• 182/91 = 2 (Factor is 91 and Remainder is 0)
• 182/182 =1 (Factor is 182 and Remainder is 0)

If we divide 182 by any numbers other than 1, 2, 7, 13, 14, 26, 91 and 182, it leaves a remainder value. Hence, the factors of 182 are 1, 2, 7, 13, 14, 26, 91 and 182.

Prime Factorization of 182

The prime factorization of 182 is the method of writing the number 182 in the form of a product of its prime factors. Since 182 is composite, it can be further factored into its prime factors. Go through the following procedure to find the prime factors of 182 using the prime factorization method.

Consider a pair factor of 182, say (1, 182)

Now, write the number 182 in terms of its prime factors. Thus, 182 is written as the product of 13 and 14. Here, 13 is a prime number and 14 is a composite number, which can again split as the product of 2 and 7.

Thus, 182 is written as 2 × 7 × 13.

Therefore, the prime factorization of 182 is 2 × 7 × 13 or 2¹ × 7¹ × 13¹, where 2, 7 and 13 are prime numbers.

We can easily find the number of factors of 182 with the help of the prime factorization method. As discussed above, the prime factorization of 182 is 2¹ × 7¹ × 13¹. The exponent values in the prime factorization of 182 are 1, 1 and 1. Now, add the number 1 to the exponent values and then multiply with the obtained values.

(i.e.) (1+1)×(1+1)×(1+1) = 2×2×2 = 8

Hence, the number 182 has 8 factors.
