First note that prime numbers are all positive integers that can only be evenly divided by 1 and itself. Prime Factors of 105 are all the prime numbers that when multiplied together equal 105.
How to find the Prime Factors of 105 The process of finding the Prime Factors of 105 is called Prime Factorization of 105. To get the Prime Factors of 105, you divide 105 by the smallest prime number possible. Then you take the result from that and divide that by the smallest prime number. Repeat this process until you end up with 1. This Prime Factorization process creates what we call the Prime Factor Tree of 105. See illustration below.

All the prime numbers that are used to divide in the Prime Factor Tree are the Prime Factors of 105. Here is the math to illustrate: 105 ÷ 3 = 3535 ÷ 5 = 77 ÷ 7 = 1 Again, all the prime numbers you used to divide above are the Prime Factors of 105. Thus, the Prime Factors of 105 are: 3, 5, 7.
How many Prime Factors of 105? When we count the number of prime numbers above, we find that 105 has a total of 3 Prime Factors.

Product of Prime Factors of 105

The Prime Factors of 105 are unique to 105. When you multiply all the Prime Factors of 105 together it will result in 105. This is called the Product of Prime Factors of 105. The Product of Prime Factors of 105 is: 3 × 5 × 7 = 105

Factors of 105 are the numbers that divide 105 perfectly without leaving any remainder.

The factors of 105 are 1, 3, 5, 7, 15, 21, 35, and 105.

To calculate the factors of 105, we can use the division method. Let's start with 1.

105 ÷ 1 leaves remainder 0.

Since 105 is not an even number, 2 does not divide 105 completely. Thus, it leaves a remainder.

105 ÷ 3 leaves remainder 0.

105 ÷ 5 leaves remainder 0.

105 ÷ 7 leaves remainder 0.

105 ÷ 15 leaves remainder 0.

105 ÷ 21 leaves remainder 0.

105÷ 35 leaves remainder 0.

105 ÷ 105 leaves remainder 0.

Thus, the factors of 105 that we have obtained are 1, 3, 5, 7, 15, 21, 35, and 105.

Prime factorization means expressing a composite number as the product of its prime factors.

Prime factorization of 105 = 3 × 5 × 7. We can determine the other composite factors of 105 from its prime factors. We can see that 35 is a factor of 105. Similarly, 15 and 21 are also factors of 105.

The pair of numbers that give 105 on multiplication are the factors of 105 in pairs. Look at the rainbow below. We start from 1 and move forward by including the numbers that give us 105 as their product.

We get the following combinations: 1 × 105, 3 × 35, 5 × 21, and 7 × 15.

All the numbers have at least two factors. 105 will have the first factor as 1 and the other factor is 105 itself.
Factors of 105 are all the possible numbers 105 is divisible by. They may be prime numbers or composite numbers.
Factors are always integers. They can never be fractions or decimals.

Example 1: 105 students are to be divided into groups such that there are an equal number of students in each group. In how many ways can they be grouped?

Solution:

We will use the concept of factor pairing to divide 105 students into groups.

We know that (35, 3), (5, 21), and (7, 15) are the factor pairs of 105.

Thus, the students can be grouped in three different ways.
Example 2: Emily has a chocolate box with 105 chocolates in it. She distributed the chocolates among her classmates. Can you find the total number of students if she gives 5 chocolate to each one of them?

Solution:

Given, total number of chocolates = 105

Chocolates given to each student = 5

Thus, the number of students in the class is = 105 ÷ 5 = 21 students.

Here we can see the numbers used, i.e. (5,21), is a pair factor of 105.
Example 3: Is there any chance that you can divide 105 geometry boxes equally among 50 kids?

Solution: Clearly, the answer is NO! Because 50 is not a factor of 105 and leaves a remainder, so we cannot distribute 105 geometry boxes to 50 kids equally.

The factors of 105 are 1, 3, 5, 7, 15, 21, 35, 105 and its negative factors are -1, -3, -5, -7, -15, -21, -35, -105.

How Many Factors of 105 are also Factors of 3?

Since, the factors of 105 are 1, 3, 5, 7, 15, 21, 35, 105 and the factors of 3 are 1, 3.
Hence, [1, 3] are the common factors of 105 and 3.

What is the Sum of all the Factors of 105?

Sum of all factors of 105 = (31 + 1 - 1)/(3 - 1) × (51 + 1 - 1)/(5 - 1) × (71 + 1 - 1)/(7 - 1) = 192

What is the Greatest Common Factor of 105 and 97?

The factors of 105 are 1, 3, 5, 7, 15, 21, 35, 105 and the factors of 97 are 1, 97. 105 and 97 have only one common factor which is 1. This implies that 105 and 97 are co-prime.

Hence, the Greatest Common Factor (GCF) of 105 and 97 is 1.
