Show Factorization for 143

<-- Enter Number

Show all factor pairs, prime factorization (factor tree), sum of factors (divisors), aliquot sum, and prime power decomposition of 143.

We do this by listing out all pairs of numbers greater than 0 and less than or equal to 143 who have a product equal to 143:
143 = 1 x 143
143 = 11 x 13

There are 2 factor pairs of 143.

List factors of 143
1, 11, 13, 143

List odd factors of 143
1, 11, 13, 143

List even factors of 143


Calculate proper factors of 143
Proper factors are all factors except for the number itself, in this case 143
1, 11, 13

Now, show the prime factorization (factor tree) for 143 by expressing it as the product of ALL prime numbers.
143 = 11 x 13 <--- 11 is a prime number

Next step is to reduce 13 to the product of prime numbers:
Our prime factorization (factor tree) is as follows:
11 x 13

No prime power decomposition exists since there are no duplicate prime numbers in the prime factorization:

Show the sum of factors (divisors) for 143
1 + 143 + 11 + 13 = 168

Show the aliquot sum:
The aliquot sum is the sum of all the factors of a number except the number itself
1 + 11 + 13 = 25
