- 25 × 44 = 1100
Finding Factors Using the 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: 1100 ÷ 1 = 1100
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 1100 are 1, 2, 4, 5, 10, 11, 20, 22, 25, 44, 50, 55, 100, 110, 220, 275, 550, and 1100.
Prime Factors and Prime Factorization:
Multiplying prime numbers to get the given number as their product is called prime factors. A number, when simplified using its prime factors, is expressed in the form of prime factorization.
Prime Factors of 1100: Number 1100 has the prime factors 2, 5, and 11.
To find the prime factors of 1100, divide 1100 by the prime numbers like 2, 5, and 11 from the list of factors of 1100.
Step 1: Divide 1100 by the prime number 2
1100 ÷ 2 = 550
Step 2: Divide 550 by 2
550 ÷ 2 = 275
Step 3: Divide 275 by 5
275 ÷ 5 = 55
Step 4: Divide 55 by 5
55 ÷ 5 = 11
Step 5: Divide 11 by 11
11 ÷ 11 = 1
Prime Factorization of 1100: Prime factorization breaks down the prime factors of 1100.

Factors of 1100 Examples
Problem 1
Can you check whether 100 and 1100 are co-prime?
No, 100 and 1100 are not co-prime
Explanation
To check whether two numbers are co-prime, list their factors first. Once you have listed the factors, identify the common factors and determine the GCF. If the GCF is greater than 1, then the numbers are not co-prime.
Factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100
Factors of 1100: 1, 2, 4, 5, 10, 11, 20, 22, 25, 44, 50, 55, 100, 110, 220, 275, 550, 1100
Here, the GCF is 50. So, 100 and 1100 are not co-prime. For co-prime, the GCF of numbers should be 1.
Problem 2
Verify whether 1100 is a multiple of 5
Yes, 1100 is a multiple of 5
Explanation
A multiple of 5 is a number that ends in 0 or 5. Since 1100 ends in 0, it is a multiple of 5.
Problem 3
Identify the perfect square from the factors of 1100
The perfect square factors of 1100 are 1, 4, 100, and 400
Explanation
A perfect square is a number we get when the same number is multiplied twice. For example, 4 is 2×2, 100 is 10×10, and 400 is 20×20.
Problem 4
Check if 1100 is divisible by 25
Yes, 1100 is divisible by 25
Explanation
A number is divisible by 25 if it ends in 00 or the last two digits are divisible by 25. Since 1100 ends in 00, it is divisible by 25.
Problem 5
Find the common factors of 100 and 1100
The common factors of 100 and 1100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100
Explanation
To find the common factors, list the factors of each number and identify the numbers that appear in both lists.
