What are the factors of 143

143 is not a prime number, so it has multiple positive integer factors. To find these factors, one method is to use the prime factorization of 143 which consists of 11 and 13 multiplied together (11 * 13 =143). This indicates that there are two distinct core numbers contributing to its makeup: an individual factor each for 11 and 13. When added up in total there are 4 different positve integers that divide evenly into 143 – 1, 11 ,13  & 143 itself!

How to Find Factors of 143

The following are the methods through which the factors of 143 can be found: 

  • The factor of 143 using Multiplication Method
  • Factors of 143 using the Division Method
  • Prime Factorization of 143
  • Factor tree of 143

Factors of 143 using Multiplication Method

Breaking 143 down to its prime factors is a great way of understanding it from the core. The prime factorization of this number can be expressed not only as 1 x 143 but also in exponential notation: 143^1.
To find out all about the components that make up any given number, simply divide by the smallest possible primes and track how those quotients change! A visual representation like a Factor Tree will provide an easy-to-understand picture showing each part that contributes to making up one single entity – what wonders lie underneath every base figure we see everyday!

Factors of 143 Using Division Method

Finding the factors of a number can be relatively straightforward when using the division method. In this case, we’re looking for all numbers that will divide evenly into 143: 1, 11, 13, and 143 – each of these is what is known as ‘factors’ and in order to find them you proceed by starting with your target number (143) then dividing it by smallest positive integer first (1). If it divides evenly then the result which is obtained after calculation becomes one factor otherwise not! After exhausting 1 if there’s still any remainder left or the number needs further factoring, follow up next step i.e., Continuous Division of the same Target Number by remaining Smallest Positive Integers respectively until you reach the given value itself. This process results in us 4 Different Values/Factors:

Deconstructing a number into its prime factors is known as the process of prime factorization. In this way, you can express any composite (non-prime) number by breaking it down to its unique set of primes. A great illustration of this concept lies in 143 – which consists only of 11 and 13 when taken all the way back apart through multiplication! Prime numbers cannot be deconstructed further because they are already in their simplest form; therefore, there is no simpler expression for them than what exists already.

To create a factor tree, begin by writing the number you wish to find the prime factors for at the top. Then divide that number by its smallest possible prime factor; this creates a branch of your “tree” with which all other branches will connect. Once divided, if what remains is still a prime number itself then it becomes your final branch and can be read from starting from the initial number as [initial #] = [prime divisor] * [remainder]. In our example, 143 would have an answer reading: 143 = 11 x 13.

Factor Pairs of 143

Calculate Pair Factors of

1 x 143=143

11 x 13=143

13 x 11=143

So Pair Factors of 143 are

(13,11)

To figure out all the pairs of positive integers that can be multiplied to make 143, we have to first look at its prime factorization. When you break down a number into its two lowest possible factors (called prime numbers), in this case 11 and 13 are both needed for it equals exactly 143. That’s why these four combinations work: 1×143; 11×13; 13×11; and even itself multiplied by iself –  143 x143! Prime Numbers only have 2 factors so since there are 4 possibilities here with different integer pairings, it’s safe to say that this isn’t one of them- making our final answer clear – 143 is not a prime number.

Fun Facts of Factors of 143

  • 143 is a special composite number that can be expressed by the product of two prime numbers and having equal factors, as well as being palindromic – reading the same forward or backward. 
  • The unique combination of its components have resulted in an interesting phenomenon: although it has five total factors (1, 3, 9, 13 & 39) which add up to 65; 65 itself is not one of 143’s own factors!
