210 = 2 x 3 x 5 x 7
210 = 2 × 3 × 5 × 7 350 = 2 × 52 × 7
To solve prime factorizations, divide a composite number by prime numbers until all the factors are prime. Many people like to use a chart of some kind to help visualize the process. One kind is a factor tree. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. 2 x 3 x 5 x 7 is the prime factorization of 210.
10 = 2 × 5
2x2x13 these are all of the prime factors that multiply to equal 52
2 x 29 = 58
24 x 33 = 432
Prime factorization of 32 = 2 * 2 * 2 * 2 * 2
Prime factorizations are expressions of numbers as products of prime factors. The prime factorization of 30 is 2 x 3 x 5.
49 = 7 x 7 or 72
409 is a prime number.
233357 is a prime number.
Only composite numbershave prime factorizations. Prime factorizations must consist of only prime numbers.
