**What Is the Basic Prime Factorization Method of 87?**

The Basic prime factorization method helps to find the prime factors of 87. The following are steps given below:

**Step 1:**For this purpose, let’s divide the number 87 by its smallest prime number 3.**Step 2:**And the remainder obtained is 29. The number 29 is divisible by itself only.**Step 3:**Now, the remainder is 1. Therefore, the prime factors of 87 are 3 and 29.

The image of the prime factorization of 87 is given below:

**How to Find Factors of 87 Through Division Method?**

The division method helps to find the factors of a number by dividing the given number by the smallest prime number and again the obtained remainder is divided by the smallest number that can divide it. This process is continued till the remainder becomes 1. The steps involved in this process are given below:

- 87 ÷ 1= 87
- 87 ÷ 3 = 29
- 87÷ 29 = 3
- 87 ÷ 87 = 1

Therefore, the factors of 87 are 1, 3, 29, and 87.

**What Is the Factor Tree of 87? **

The factor tree method is really a good way to represent the factors of 87. As it shows the prime numbers and the composite numbers that can divide the given number. The steps involved in the factor tree method are given below:

**Step 1:**Let’s place the given number 87 at the top of the factor tree method and place the first pair factors of 87 in its branches which are 3 and 29.**Step 2:**The numbers 3 and 29 are not further divisible. Therefore, the prime factors of 87 are 3 and 29.

Therefore, the prime factors of 87 are 3 and 29.
