Enter the integer number you want to get its prime number factors:
Ex.: 2, 3, 4, 11, 10225, etc.

Prime number factorization consequence:

The number 245 is a composite number and then, information technology is possible to factorize it. In other words, 245 can exist divided by 1, past itself and at least by 5 and 7. A composite number is a positive integer that has at to the lowest degree ane positive divisor other than ane or the number itself. In other words, a blended number is any integer greater than one that is non a prime number.

The prime number factorization of 245 = 5•7².

The prime number factors of 245 are five and 7.

What is prime factorization?

Definition of prime factorization

The prime factorization is the decomposition of a composite number into a product of prime number factors that, if multiplied, recreate the original number. Factors by definition are the numbers that multiply to create another number. A prime number is an integer greater than one which is divided only past one and by itself. For example, the only divisors of 7 are one and 7, so 7 is a prime, while the number 72 has divisors deived from 2³•3² similar 2, iii, 4, half-dozen, eight, 12, 24 ... and 72 itself, making 72 not a prime. Note the the just "prime number" factors of 72 are 2 and three which are prime numbers.

Prime factorization example 1

Let'due south detect the prime number factorization of 72.

Solution ane

Start with the smallest prime that divides into 72, in this case 2. We tin write 72 equally:
72 = two x 36
Now find the smallest prime that divides into 36. Once more nosotros can use 2, and write the 36 every bit two ten 18, to requite.
72 = ii x 2 ten xviii
18 also divides by 2 (18 = 2 x 9), so we have:
72 = 2 x 2 x two x 9
9 divides by 3 (9 = iii x 3), then we have:
72 = 2 x 2 x 2 x 3 10 three
2, 2, 2, iii and iii are all prime numbers, and so we take our answer.

In curt, we would write the solution equally:
72 = 2 x 36
72 = ii x 2 x 18
72 = ii ten 2 x 2 x 9
72 = 2 10 2 x 2 x 3 x three
72 = ii^three x 3^two (prime factorization exponential form)

Solution two

Using a gene tree:

Procedure:
Find two factors of the number;
Look at the ii factors and determine if at to the lowest degree one of them is not prime;
If it is non a prime factor it;
Echo this process until all factors are prime.

See how to gene the number 72:

72
/  \
2   36
/  \
two   xviii
/  \
ii    nine
/  \
3    3

72 is non prime --> carve up by ii

36 is not prime number --> separate by ii

eighteen is not prime --> split up past ii

9 is not prime --> dissever by iii

3 and three are prime --> stop

Taking the left-hand numbers and the right-most number of the last row (dividers) an multiplying and then, we take

72 = 2 x ii ten 2 10 iii x 3

72 = 2³ x 3² (prime number factorization exponential class)

Notation that these dividers are the prime factors. They are as well called the leaves of the factor tree.

Prime number factorization example 2

Run across how to factor the number 588:

588
/  \
ii  294
/  \
ii  147
/  \
3   49
/  \
7    7

588 is not prime --> divide by 2

294 is not prime --> divide by 2

147 is not prime number --> split by 3

49 is not prime --> divide past 7

7 and 7 are prime number --> stop

Taking the left-hand numbers and the right-most number of the concluding row (dividers) an multiplying then, we have

588 = ii ten two ten 3 x vii ten 7
588 = 2² ten three x vii^two (prime number factorization exponential class)
