Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 1263, how they are used in real life, and tips to learn them quickly.

What are the Factors of 1263?

The numbers that divide 1263 evenly are known as factors of 1263. A factor of 1263 is a number that divides the number without remainder. The factors of 1263 are 1, 3, 421, and 1263.

Negative factors of 1263: -1, -3, -421, and -1263.

Prime factors of 1263: 3 and 421.

Prime factorization of 1263: 3 × 421.

The sum of factors of 1263: 1 + 3 + 421 + 1263 = 1688

How to Find Factors of 1263?

Factors can be found using different methods. Mentioned below are some commonly used methods:

  1. Finding factors using multiplication
  2. Finding factors using division method
  3. Prime factors and Prime factorization

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 1263. Identifying the numbers which are multiplied to get the number 1263 is the multiplication method.

Step 1: Multiply 1263 by 1, 1263 × 1 = 1263.

Step 2: Check for other numbers that give 1263 after multiplying

3 × 421 = 1263

Therefore, the positive factor pairs of 1263 are: (1, 1263), (3, 421). All these factor pairs result in 1263. For every positive factor, there is a negative factor.

Finding Factors Using Division Method

Dividing the given numbers with the whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 1263 by 1, 1263 ÷ 1 = 1263.

Step 2: Continue dividing 1263 by the numbers until the remainder becomes 0.

1263 ÷ 1 = 1263

1263 ÷ 3 = 421

Therefore, the factors of 1263 are: 1, 3, 421, 1263.

Prime Factors and Prime Factorization

The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:

Using Prime Factorization: In this process, prime factors of 1263 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1263 ÷ 3 = 421

421 is a prime number. The prime factors of 1263 are 3 and 421. The prime factorization of 1263 is: 3 × 421.

Factor Tree

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -

Step 1: Firstly, 1263 is divided by 3 to get 421.

Step 2: 421 is already a prime number and cannot be divided further. So, the prime factorization of 1263 is: 3 × 421.

Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.

  • Positive factor pairs of 1263: (1, 1263), (3, 421).
  • Negative factor pairs of 1263: (-1, -1263), (-3, -421).

Common Mistakes and How to Avoid Them in Factors of 1263

Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.

Problem 1

There are 3 groups and 1263 marbles. How will they divide it equally?

Okay, lets begin

They will get 421 marbles each.

Explanation

To divide the marbles equally, we need to divide the total marbles with the number of groups.

1263/3 = 421

Well explained 👍

Problem 2

A field is rectangular, the length of the field is 421 meters and the total area is 1263 square meters. Find the width?

Okay, lets begin

3 meters.

Explanation

To find the width of the field, we use the formula,

Area = length × width

1263 = 421 × width

To find the value of the width, we need to shift 421 to the left side.

1263/421 = width

Width = 3.
