How To Find Factors of 215 Through Division Method?

As we know that the factors of 215 can be found through the division method, we should learn and understand it now. Through this method, you will divide 215 with all integers till the remainder becomes 1. Ones that will leave no remainder after being divided by 215, are known as factors of 215. This is quite a long procedure. Let’s head right into it.

215 ÷ 1 = 215

215 ÷ 5 = 54

215 ÷ 43 = 5

215 ÷ 215 = 1

As we can see, only 1, 5, 43, and 215 get completely divided by 215 without a remainder being left. So, we can conclude that 1, 5, 43, and 215 are the factors of 215.

What Is the Prime Factorization of 215?

There is a method to find prime factors of 215. This method is called prime factorization. Let us go through step by step to understand how this method works:

Step 1: Firstly, we will take 215. Now, we will take a factor of 215 to divide it.

Step 2: So, we will choose 5 to divide it with.

215 ÷ 5 = 43

Step 3: As we can see, we have 43, but since 43 is a composite number, it can only be divided by 1 or 43 itself. So, we will divide 43 by 43.

43 ÷ 43 = 1

Step 4: Since we have reached one as quotient, we cannot divide it anymore.

Hence, we can conclude that 5 X 43 or 5¹ X 43¹ are the prime factors of 215. We can also write it down as 5 and 43, as both of them are prime numbers.

What is the Factor Tree of 215?

Students can also use the factor tree to find the prime factors of 215. In this method, we will place the number 215 at the top of the factor tree. Now, as part of the branches, we will write down any set of pair factors of the given number (215). Now, again, we will split the pair of factors into factors. This process will be continued until the branches become prime numbers. Now, circling all the prime numbers will give us the prime factors of 215.

Step 1: Let’s place the number 215 at the top of the factor tree and write down 215 in pairs, that is, 5 and 43.

Step 2: We can see that 5 and 43 are both prime numbers. The branches in the factor tree will now be all the prime numbers.

Hence, circling all the branches, 5¹ X 43¹ or 5 X 43= 215, which are 215 prime factors.

There are many ways in which we can write the factor tree of 215. Below is an image representation of the factor tree of 215:
