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.
by reducing the number you started with until you can't reduce anymore so
all the numbers left will be prime ex. 100=10x10 both tens are not prime so keep going... 2x5 and 2x5 you're answer is 2x2x5x5 which equals 100
You start by writing the number you have to factorize at the top of the tree. You then draw 2 lines leading off from that number and write 2 factors of the number below the lines. You continue to draw of lines from those numbers until all of the numbers in one line are prime unless they are variables you don't know the equivalent of.

2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.
What is the greatest common factor of 525 and 735
You can think of a factor as a number that divides another number with no remainder. For example, 3 is a factor of 6 since 3 goes into 6 two times with no remainder. Now if the factor is prime, then it is a prime factor. So in the example above, 3 is a prime factor. This is because the factor itself has only two factors, 1 and itself. 6 goes into itself also, but since 6 is not prime, it is not a prime factor. Now that you understand it, here is a more precise definition. A prime factor is a factor that is a prime number. In other words, one of the prime numbers that, when multiplied, give the original number.
The GCF of 14, 31, 39, and 56 is 1. One way to solve the problem is to notice that 31 is prime, and can't possibly be a factor of 14, which is smaller.If you prefer, you can write the prime factorization of each number in the set and find the GCF:The prime factorization of 14 is 2*7The prime factorization of 31 is 31 (1*31)The prime factorization of 39 is 3*39The prime factorization of 56 is 2*2*2*7So the GCF is 1.
A kilogram is a unit of measurement for mass. It is not a number that can be factorised!
No prime power exists since there are no duplicate prime numbers in the prime factorization.
a factor tree
The purpose of a factor tree is to notate the process of finding the prime factorization. If a number is already prime, a factor tree is not necessary.
A factor tree.
The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
write the prime factorization of 625
726 363,2 121,3,2 11,11,3,2
79 is a prime number. The only two factors of a prime number are 1 and itself.The only prime factor of 79 is 79. There is only one prime factor of a prime number - itself.The distinct prime factor (listing each prime factor only once) of 79 is also 79.The prime factorization of 79 is 79. In some cases, to emphasize that it is prime, you might write the prime factorization as 1 x 79.
That's known as the prime factorization. It's the bottom branch of the factor tree. The prime factorization of 210 is 2 x 3 x 5 x 7.
write the prime factorization of the number. simple as that.
You don't. 13 is a prime number.
