How to Find Factors of 1261?
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 1261. Identifying the numbers which are multiplied to get the number 1261 is the multiplication method.
Step 1: Multiply 1261 by 1, 1261 × 1 = 1261.
Step 2: Check for other numbers that give 1261 after multiplying 37 × 34 = 1261
Therefore, the positive factor pairs of 1261 are: (1, 1261) and (37, 34). All these factor pairs result in 1261. 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 1261 by 1, 1261 ÷ 1 = 1261.
Step 2: Continue dividing 1261 by the numbers until the remainder becomes 0.
1261 ÷ 1 = 1261
1261 ÷ 37 = 34
Therefore, the factors of 1261 are: 1, 37, and 1261.
Prime Factors and Prime Factorization
The factors can be found by dividing it with a prime number. 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 1261 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1261 ÷ 37 = 34
34 ÷ 17 = 2
2 ÷ 2 = 1
The prime factor of 1261 is 37. The prime factorization of 1261 is: 37 × 34.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1261 is divided by 37 to get 34.
Step 2: Now divide 34 by 17 to get 2.
Step 3: Divide 2 by 2 to get 1. So, the prime factorization of 1261 is: 37 × 34.
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 1261: (1, 1261) and (37, 34).
- Negative factor pairs of 1261: (-1, -1261) and (-37, -34).
Common Mistakes and How to Avoid Them in Factors of 1261
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 1261, 1 and 1261 are also factors.
Mistake 2
Missing Negative Factors
We have used only to mention positive factors every time. There are also negative factors, always check whether you have mentioned negative factors. For example, the factors of 1261 consist of -1, -37, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions also as factors. Only whole numbers can be factors. For example, thinking 1.5 as a factor, because 1261/1.5 = 840.666, 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 1261 are prime numbers. For example, 37 is the prime factor of 1261, but it has other factors like 1, 1261.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors. For example, not breaking 1261 as 37 × 34 and missing all the key factors.

Factors of 1261 Examples
Problem 1
There are 37 students and 1261 pencils. How will they divide them equally?
They will get 34 pencils each.
Explanation
To divide the pencils equally, we need to divide the total pencils by the number of students.
1261/37 = 34
Problem 2
A painting is rectangular, the length of the painting is 37 cm and the total area is 1261 square cm. Find the width?
34 cm.
Explanation
To find the width of the painting, we use the formula,
Area = length × width
1261 = 37 × width
To find the value of width, we need to shift 37 to the left side.
1261/37 = width
Width = 34.
Problem 3
There are 2 tables and 1261 marbles. How many marbles will be on each table?
Each table will have 630 marbles.
Explanation
To find the marbles on each table, divide the total marbles by the tables.
1261/2 = 630.5
Since the division does not result in a whole number, we cannot divide marbles equally between two tables.
Problem 4
In a factory, there are 1261 machines, and 34 departments. How many machines are there in each department?
There are 37 machines in each department.
Explanation
Dividing the machines by the total departments, we will get the number of machines in each department.
1261/34 = 37
Problem 5
1261 plants need to be arranged in 37 sections. How many plants will go into each section?
Each of the sections has 34 plants.
Explanation
Divide total plants by sections.
1261/37 = 34
