### Example: Find factors of 1851

• Divide 1851 by 1: 1851 ÷ 1 : Remainder = 0
• Divide 1851 by 3: 1851 ÷ 3 : Remainder = 0
• Divide 1851 by 617: 1851 ÷ 617 : Remainder = 0
• Divide 1851 by 1851: 1851 ÷ 1851 : Remainder = 0

Hence, Factors of 1851 are 1, 3, 617, and 1851

#### 2. Steps to find factors of 1851 using Prime Factorization

A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.

There are two different methods that can be used for the prime factorization.

#### Method 1: Division Method

To find the primefactors of 1851 using the division method, follow these steps:

• Step 1. Start dividing 1851 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
• Step 2. After finding the smallest prime factor of the number 1851, which is 3. Divide 1851 by 3 to obtain the quotient (617).
1851 ÷ 3 = 617
• Step 3. Repeat step 1 with the obtained quotient (617).
617 ÷ 617 = 1

So, the prime factorization of 1851 is, 1851 = 3 x 617.

#### Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 1851 as shown below:

So, the prime factorization of 1851 is, 1851 = 3 x 617.

#### 3. Find factors of 1851 in Pairs

Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 1851 would be the two numbers which, when multiplied, give 1851 as the result.

The following table represents the calculation of factors of 1851 in pairs:

Factor Pair Pair Factorization
1 and 1851 1 x 1851 = 1851
3 and 617 3 x 617 = 1851

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 1851. They are called negative pair factors.

Hence, the negative pairs of 1851 would be ( -1 , -1851 ) , ( -3 , -617 ) .

#### How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

#### Properties of factors

• Every number is a factor of zero (0), since 1851 x 0 = 0.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Every factor of a number is an exact divisor of that number, example 1, 3, 617, 1851 are exact divisors of 1851.
• Factors of 1851 are 1, 3, 617, 1851. Each factor divides 1851 without leaving a remainder.
