Answer for screen readers
The factors of 128 are: 1, 2, 4, 8, 16, 32, 64, and 128.
Steps to Solve

Identify the definition of factors Factors are the integers that can divide a number without leaving a remainder. Therefore, we need to find all the whole numbers that evenly divide 128.

Start dividing from 1 to 128 Begin testing each whole number starting from 1. We will divide 128 by each number and check if the result is a whole number.

List the factors Continue this process until reaching 128. If the division results in a whole number, add that number to the list of factors.
For instance, checking:
 ( 128 \div 1 = 128 ) (Factor)
 ( 128 \div 2 = 64 ) (Factor)
 ( 128 \div 4 = 32 ) (Factor)
 ( 128 \div 8 = 16 ) (Factor)
 ( 128 \div 16 = 8 ) (Factor)
 ( 128 \div 32 = 4 ) (Factor)
 ( 128 \div 64 = 2 ) (Factor)
 ( 128 \div 128 = 1 ) (Factor)
 Complete the list of factors At the end of this process, we will have found all the factors of 128.
The factors of 128 are: 1, 2, 4, 8, 16, 32, 64, and 128.
More Information
128 is a composite number, meaning it has factors other than 1 and itself. It is also a power of 2, specifically $2^7$. This is why its factors are all powers of 2.
Tips
 Forgetting to test all numbers up to 128.
 Misidentifying the factors by skipping some or not dividing properly.
