How do you find prime factorization of a number?

Answer 1

Prime factors are numbers that can only be divided by one

Example: The number "2" is prime, because I cannot divide 2 by any number except 1.

A Prime number could be "10" because I can mulitply 2X5, or 10X1.

Answer 2

you will have to divide it by the highest number. people can use trees like this.

40

^

(20)(2)

^

(10)(2)

^

(5)(2)

like that. you divide the numbers u can divide.so the answer will be:

5*2*2*2 or 5*2to the power of 3

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.
