Factors of 215
The factors of 215 are the numbers or integers that divide the original number, evenly. There is a total of four factors of 215, they are 1, 5, 43 and 215. The smallest factor is 1 and the greatest factor is 215, itself.
If two factors are multiplied together to generate 215, they become the pair factors of 215. Hence, the pair factors are (1, 215 and (5, 43). The prime factors of 215 are 5 × 43. If we add all the factors of 215, then the sum will be 264.
In this article, we will learn how to find factors, prime factors and pair factors of 215, step by step. This is possible using prime factorisation and division methods. Click here to get the factors of 1 to 100.
What are the Factors of 215?
The factors of 215 are the numbers that divide 215 exactly without leaving a remainder. As the number 215 is a composite number, it has more factors other than 1 and 215. We can say, 215 is an odd composite number. Hence, the factors of 215 are 1, 5, 43 and 215. Similarly, the negative factors of 215 are -1, -5, -43 and -215.
How to Find Factors of 215?
To find the factors of 215 there are two methods:
- Division method
- Prime factorisation method
Factors of 215 by Division Method
We know that the factors of a number can be found using two different methods, such as the division method and the prime factorization method. Now, let us first start with the division method.
In the division method, the number 215 is divided by different consecutive integers. If the integer divides 215 completely and leaves the remainder 0, then the integers are the factors of 215. Go through the following procedure to find the factors of 215.
- 215/1 = 215 (Factor is 1 and remainder is 0)
- 215/5 = 43 (Factor is 5 and remainder is 0)
- 215/43 = 5 (Factor is 43 and remainder is 0)
- 215/215 = 1 (Factor is 215 and remainder is 0)
If we divide 215 by any numbers other than 1, 5, 43 and 215, it leaves the remainder of some value. Hence, the factors of 215 are 1, 5, 43 and 215.
Prime Factorization of 215
In the prime factorization of 215, the number 215 is written as the product of its prime factors. Go through the following steps to find the prime factors of 215.
- Let us take the number 215 and its pair factors as (1, 215).
- We know that 215 is an odd composite number and it can be split further into its prime factors.
- Thus, 215 is written as the product of 5 and 43.
- Now, both the numbers 5 and 43 are prime factors and it cannot be further factored.
- Thus, 215 is written as the product of 1, 5 and 43. (i.e.) 215 = 1× 5 × 43
- Hence, the prime factorization of 215 is 5×43 or 5^{1} × 43^{1}.
It is possible to find the exact number of factors of a number 215 with the help of prime factorisation. The prime factor of the 215 is 5 x 43. The exponents in the prime factorisation are 1, and 1. Add the number 1 with the exponents and multiply it. (1+1)(1+1) =2 x 2= 4. Therefore, the number 215 has 4 factors.
Pair Factors of 215
To find the pair factors of 215, multiply the two numbers in a pair to get the original number as 215. The pair factors of 215 can be positive or negative, but they cannot be decimal or fraction. Thus, the positive and negative pair factors of 215 are given below:
Positive Pair Factors of 215:
