How to Find Factors of 1266?
Factors can be found using different methods. Mentioned below are some commonly used methods:
- Finding factors using multiplication
- Finding factors using division method
- 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 1266. Identifying the numbers which are multiplied to get the number 1266 is the multiplication method.
Step 1: Multiply 1266 by 1, 1266 × 1 = 1266.
Step 2: Check for other numbers that give 1266 after multiplying
2 × 633 = 1266
3 × 422 = 1266
6 × 211 = 1266
Therefore, the positive factor pairs of 1266 are: (1, 1266), (2, 633), (3, 422), (6, 211). All these factor pairs result in 1266. 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 in whole numbers as factors. Factors can be calculated by following a simple division method -
Step 1: Divide 1266 by 1, 1266 ÷ 1 = 1266.
Step 2: Continue dividing 1266 by the numbers until the remainder becomes 0.
1266 ÷ 1 = 1266
1266 ÷ 2 = 633
1266 ÷ 3 = 422
1266 ÷ 6 = 211
Therefore, the factors of 1266 are: 1, 2, 3, 6, 211, 422, 633, 1266.
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
- Using factor tree
Using Prime Factorization: In this process, prime factors of 1266 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1266 ÷ 2 = 633
633 ÷ 3 = 211
211 ÷ 211 = 1
The prime factors of 1266 are 2, 3, and 211. The prime factorization of 1266 is: 2 × 3 × 211.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1266 is divided by 2 to get 633.
Step 2: Now divide 633 by 3 to get 211.
Step 3: Here, 211 is a prime number that cannot be divided anymore. So, the prime factorization of 1266 is: 2 × 3 × 211.
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 1266: (1, 1266), (2, 633), (3, 422), (6, 211).
- Negative factor pairs of 1266: (-1, -1266), (-2, -633), (-3, -422), (-6, -211).
Common Mistakes and How to Avoid Them in Factors of 1266
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
Mistake 1
Forgetting the number itself and 1 is a factor
Children might forget to add the given number itself and 1 as a factor. The number itself and 1 are the factors for every number. Always remember to include 1 and the number itself. For example, in factors of 1266, 1 and 1266 is also a factor.
Mistake 2
Missing Negative Factors
We often mention only positive factors. There are also negative factors, always check whether you have mentioned negative factors. For example, the factors of 1266 consist of -1, -2, -3, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions as factors. Only whole numbers can be a factor. For example, thinking 1.5 as a factor is incorrect because 1266/1.5 = 844, and it is not a whole number.
Mistake 4
Confusing Factors With Prime Numbers
Remember that factors can be any whole numbers, not only just primes. For example, thinking all the factors of 1266 are prime numbers. For example, 2, 3, and 211 are the prime factors of 1266, but it has other factors like 6, 422.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors. For example, not breaking 1266 as 2 × 3 × 211 and missing all the key factors.

Factors of 1266 Examples
Problem 1
There are 6 friends and 1266 chocolates. How will they divide it equally?
They will get 211 chocolates each.
Explanation
To divide the chocolates equally, we need to divide the total chocolates with the number of friends.
1266/6 = 211
Problem 2
A rectangular field has a length of 211 meters and a total area of 1266 square meters. Find the width.
6 meters.
Explanation
To find the width of the field, we use the formula,
Area = length × width
1266 = 211 × width
To find the value of width, we need to divide the area by the length.
1266/211 = width
Width = 6.
Problem 3
There are 3 boxes and 1266 marbles. How many marbles will be in each box?
Each box will have 422 marbles.
Explanation
To find the marbles in each box, divide the total marbles by the boxes.
1266/3 = 422
Problem 4
In a school, there are 1266 students, and they are divided into 211 groups. How many students are there in each group?
There are 6 students in each group.
Explanation
Dividing the students by the total number of groups, we will get the number of students in each group.
1266/211 = 6
Problem 5
1266 apples are to be arranged into 126 cartons. How many apples will be in each carton?
Each carton will have 10 apples.
Explanation
Divide total apples by the number of cartons.
1266/126 = 10
