Factors and Multiples vs Prime Factorization Deluxe

Factors and Multiples app use cell division concept to help kids to learn prime factorization and how to find LCM and GCF. if you are interested in this app, you can watch the following video: https://www.youtube.com/watch?v=TjxcZ2ihk-I This app include 6 functions are as follows: 1. 100 Numbers chart : Prime numbers chart, Composite numbers chart, Multiples of 2, Multiples of 3, Multiples of 5, Multiples of 7, Multiples of 10, Multiples of 11. You can click the circle on the composite numbers chart to drill down to that number's prime factorization (factor tree and division method) 2. Pick the prime numbers game: Place the prime numbers by dragging and dropping to the circle area and avoid dragging and dropping the composite numbers. 3. Pick the composite numbers & Prime Factorization game Place the composite numbers by dragging and dropping to the circle area and avoid dragging and dropping the prime numbers. When the composite number in the circle, you can long press it 1 second , then you can see it’s prime factorization. 4. Learn how to find Least Common Multiple It provide 2 method to help kids to learn LCM,the methods are as follows: a. List all the Multiples of Both Numbers b. Division Ladder ( Division by primes ) 5. learn how to find Greatest Common Factor It provide 3 method to help kids to learn GCF,the methods are as follows: a. List all the factors of Both Numbers b. Prime Factorization c. Division Ladder ( Division by primes ) 6. Find the GCF and LCM using prime factorization This function provide step by step method to help kids learn how to find the GCF and LCM. Step 1. Long press 1 second on the first composite number to see it’s prime factorization ,until there are no composite number. Then you can click the next button to go to step 2. Step 2. Long press 1 second on the second composite number to see it’s prime factorization ,until there are no composite number. Then you can click the next button to go to step 2. Step 3. Place the factors in the correct location Step 4. Click the next button , you can see how to calculate LCM and GCF As a MOMs with Apps member,we follow the "Know What's inside" best practices for kids' apps. http://momswithapps.com/

Use Prime Factorization Deluxe to explore and learn how to find the prime factorization of a composite number. Use the slider to select a number up to 100 for factorization. If a composite number is selected the app prompts the user to select a factor using the slider. If a prime is selected it is indicated using a red marker. Tap the question mark for a random number up to 100 to be automatically selected. Choose factors for the given number to build a factor tree. Continue until the prime factorization has been found. Learn how to find the Greatest Common Factor (GCF) and Least Common Multiple (LCM). For GCF, use the number line slider to select two numbers. The factors of the two numbers are show in a table and the greatest common factor is highlighted. For LCM, choose two numbers. The multiples of the number are shown in a table. The least common multiple is highlighted in the table. The first step in the process of prime factorization is to select a factor for the given number. If a factor is selected a branch on the tree is filled in. This process continues until all the composite numbers in the tree have been factored leaving only primes. Composite numbers are shown in blue and primes are highlighted in red. By examing the prime factorizations of two numbers students will notice that the Greatest Common Factor of two numbers is precisely the product of the primes that are common to both. Therefore it follows that the common multiples of any two numbers must contain each of the primes exactly once and that the least common multiple is the smallest number that occurs in both sets.
