How to list the prime factors of a number?
You need to Writ edown all the factors.. :)
How can you use the rectangles models for a number to list the factors of the number?
24
Is it possible to list all the factors of a number?
Yes.
Why does a square number always have an odd number of factors?
Factors can be listed as factor pairs. With square numbers, one of those pairs will be the same number twice. When written as a list, only one of them will be used, leaving an odd number of factors.
How do you work out the HCF of two numbers?
-- List all the factors of the first number.-- List all the factors of the second number.-- Find any factors that appear on both lists.-- The highest one of those is the HCF of the two original numbers.
What number has the most factors between 1 and 1100?
The answer between 1 and 1000 is 840, but what about 1 and 1100?
What is the difference between listing the factors and listing the multiples of a number?
The list of factors of a number is a list of numbers that divide evenly into it. A list of multiples of a number is just a list of numbers that the first number divides. Example Factors of 6: 1,2,3,6 Multiples of 6: 6,12,18...
What are the prime factors of 1100?
As a product of its prime factors: 2*2*5*5*11 = 1100 or as 22*52*11 = 1100
What lists factors is it called common factors or composite number or multiple?
When you are finding common factors, one method is to list the factors.
What is the list number of factors that a number can have?
1 has one factor
What are concepts to finding the greatest common factor?
-- List all factors of the first number. -- List all factors of the second number. -- If there are more than two numbers, list all factors of each one. -- Find the set of factors that are on every list. -- Find the greatest factor in the set.
What is factors that appear in a complete list of factors for a given number only once?
distinct factors
What number between 1 and 25 has the list factors?
1 has the least factors.
How to list the prime factors of a number?

What is the difference between finding the factors of a number and finding the prime factors of a number?
No difference. Once you've found the factors of a number, the prime numbers on that list are the prime factors.
What type of number has an odd number of factors?
A perfect square has an odd number of factors. Factors of numbers always come in pairs -- except for perfect squares. Since the square root of a perfect square is listed only once on the list of factors, it results in a list with an odd number of factors.
