Finding Factors Using Multiplication Method
The multiplication method finds the pair of factors that give 550 as their product.
Step 1: Find the pair of numbers whose product is 550.
Step 2: The factors are those numbers, when multiplied, give 550.
Step 3: Make a list of numbers whose product will be 550.
A list of numbers whose products are 550 is given below:
- 1 × 550 = 550
- 2 × 275 = 550
- 5 × 110 = 550
- 10 × 55 = 550
- 11 × 50 = 550
- 22 × 25 = 550
Thus, the factors of 550 are 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, and 550
Finding Factors Using Division Method
The division method finds the numbers that fully divide the given number. The steps are given below:
Step 1: Since every number is divisible by 1, 1 will always be a factor. Example: 550÷1=550550 \div 1 = 550550÷1=550
Step 2: Move to the next integer. The factors of the number include the number that is used to divide and the number of times the particular number is divided.
Thus, the factors of 550 are 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, and 550.
Prime Factors and Prime Factorization
The prime numbers that are present in the list of factors of a number when multiplied a certain number of times give the result as the original number. A number when it is simplified using the factors of that number and is expressed in the form of prime factors is the prime factorization of a number.
Prime Factors of 550: Number 550 has three prime factors: 2, 5, and 11.
To find the prime factors of 550:
Step 1: Divide 550 with the prime number 2.
550÷2=275
Step 2: Divide 275 with the prime number 5.
275÷5=55
Step 3: Divide 55 with the prime number 5.
55÷5=11
Step 4: Divide 11 with the prime number 11.
11÷11=1
Prime Factorization of 550: Prime Factorization breaks down the prime factors of 550, expressed as 21 × 52 × 112
Factor Tree
The prime factorization is visually represented using the factor tree. It helps to understand the process easily. In this factor tree, each branch splits into prime factors.
This tree shows the breakdown of 550 into its prime factors: 2 × 5 × 11.

Common Mistakes and How to Avoid Them in Factors of 550
Mistakes can happen when finding the factors of 550. Below are some common errors and tips on how to avoid them for accurate factor identification.
Mistake 1
Assuming 5 as the only factor of 550.
Since numbers ending in 0 or 5 are divisible by 5, you might think that 5 is the only factor of 550. Remember that factors are numbers that can divide the given number equally. Other numbers that can divide 550 completely are 1, 2, 10, 11, 22, 25, 50, 55, 110, 275, and 550.
Solved Examples for Factors of 550
Problem 1
What are the factors of 550?
The factors of 550 are 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, and 550.
Explanation
Start by testing all integers from 1 up to the square root of 550 and check divisibility. Factors are those numbers that do not leave any remainder when division is done
Problem 2
Can you check whether 275 and 110 are co-prime?
No, 275 and 110 are not co-prime.
Explanation
To determine if two numbers are co-prime, find their greatest common factor (GCF).
- Factors of 275: 1, 5, 11, 25, 55, 275
- Factors of 110: 1, 2, 5, 10, 11, 22, 55, 110
The common factors are 1, 5, 11, and 55. The GCF is 55, which is greater than 1, so the numbers are not co-prime. For numbers to be co-prime, their GCF must be 1.
Problem 3
Verify whether 550 is a multiple of 9.
The perfect square factor of 550 is 25, and its square root is 5.
Explanation
When a number is multiplied by itself and the resulting product does not have any remainder, the number is a perfect square. Among the factors of 550, 25 qualifies as it is the product of 5×5.
Problem 4
Identify the perfect square from the factors of 550.
The perfect square factor of 550 is 25, and its square root is 5.
Explanation
When a number is multiplied by itself and the resulting product does not have any remainder, the number is a perfect square. Among the factors of 550, 25 qualifies as it is the product of 5×5.
Problem 5
Is 550 a prime number?
No, 550 is not a prime number.
Explanation
Prime numbers are that, when multiplied together, give the original number. Since 550 has multiple factors, including 2, 5, 10, 11, and others, it is not prime.
