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.

How are prime factors and factors related?
Prime factors are factors that are also prime numbers.
Does any 3 digit number repeated to make a 6 digit number have to have at least 4 prime factors ex 359359 If yes then is there any pattern on how to figure that out?
abcabc=abc x 1001 1001 = 7 x 11 x 13 So such number as at least 4 prime factors: if abc is prime, then 4 factors only if abc is not prime then at least 4 factors
What are the prime factors of 5398?
The prime factors are: 2,2699
List all the factors of 44?
first you figure out what times what=44. 22x2 does. 2 is already a prime number so that is part of the end answer. THen you must figure out what times what=22 because it is NOT a prime number. 11x2 does. Now you have all prime numbers so the answer is 11x2x2
What are the factors and prime factors of 12 show the work?
The factors of 12 are: 1,2,3,4,6. The prime factors are the prime numbers in the factors. So: 1,2,3 are the prime factors of 12.
What are the factors and prime factors of 1291?
factors: 1, 1291 (prime)prime factors: 1291 (go figure!)
How do you figure out prime numbers not knowing there factors?
But you do know the factors of prime numbers. Every prime number has two factors: one and the number itself.
How do figure out the way to find the prime factors of 126 how do you figure the tree?
126 63,2 21,3,2 7,3,3,2
How do you figure out if a number is prime?
Work out if they have any factors, other than the number 1 and themselves. If they do not they are prime.
How could you figure out if numbers are prime?
You could figure out a prime number by the help of its factors. If it has only 2 factors which are 1 and number itself, then it is prime.
What is the LCM of 46 and 69?
lcm of 46 and 69 = 139 an easy way to figure this out is by multiplying together the following: prime factors they have in common * prime factors that just 46 has * prime factors just 69 has.
How do you figure out what 69 from prime or composite?
Factor it. If it has more than two factors (it has) it is composite.
How are prime factors and factors related?
Prime factors are factors that are also prime numbers.
