A factor firework is just an upside down factor tree. Write the original number at the bottom. Example: 210
7,5,3,2
35,3,2
105,2
210
7,2,2 14,2 28
42 21.2 7,3,2 7,3,2 21,2 42
prime factors
7,2,2 14,2 28
7,3,2 21,2 42
To make the factor firework for 84, you need to find all the factors of 84. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. You can use these factors to create different combinations and arrangements for the firework display.
Factor trees, ladders, fireworks, rainbows... They're all the same thing; ways to notate the prime factorization of a given number. It doesn't matter where you write the factors on the page, pick the easiest way for you to keep track of them. Example: 210 7,5,3,2 35,3,2 105,2 210
A factor tree
Factor trees, ladders, rainbows, fireworks... They're all the same thing; ways of displaying the prime factorization of a given number. The prime factorization of 28 is 2 x 2 x 7. Write it however you wish. 7,2,2 14,2 28
2,2,2,2,2,2 4,2,2,2,2 8,2,2,2 16,2,2 32,2 64
No. 10 is not a prime number, which means it cannot be a prime factor. It can be a factor, but not a prime factor.
Not a lot. They're both prime numbers. A factor that is prime is used to make other numbers.
