How do you find the product of prime numbers?

Answer 1

Taken literally, the answer to your question is multiply them together, but I'll assume you're talking about prime factorization.

All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210

210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.

2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.

Answer 2

A prime factorization shows a product of prime numbers. The answer will be something like 2 x 3 x 5 x 7 and will not include any composite numbers. If any of the equations have even numbers other than 2, eliminate them.

Answer 3

All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.

Example: 210

210 Divide by two.

105,2 Divide by three.

35,3,2 Divide by five.

7,5,3,2 Stop. All the factors are prime.

2 x 3 x 5 x 7 = 210

That's the prime factorization of 210.

Answer 4

Keep dividing by two.

2 x 2 x 2 x 2 = 16
