Understanding Factors of a Number

What is the first step in finding the factors of a number using the arc method?

• List all even numbers first

• Use a calculator to find the factors

• Begin with 1 and the number itself

• Start with the number 2 and the number itself

Why does the arc method become less effective for larger numbers?

• It requires a calculator

• It becomes clumsy and confusing with many arcs

• It only works for even numbers

• It is too slow for small numbers

What is the alternative method suggested for finding factors of larger numbers?

• Listing factor pairs on separate lines

• Using only prime numbers

• Drawing more arcs

• Using a calculator to list all numbers

Which of the following is a factor pair of 100?

• 3 and 33

• 7 and 14

• 6 and 16

• 4 and 25

How should factors be listed once they are found?

• In random order

• In descending order

• In ascending order

• In alphabetical order
