Factors of 403
Factors are the ‘building blocks’ of a number. They are the numbers that can be multiplied together to reach the number you started with. 403 is an interesting number. It is large enough to make you think, but simple enough to learn if you know a few tricks. Let’s dive into it!
What are the factors of 403?
Factors are whole numbers that, when multiplied, the product is equal to 403.
403 is not a prime number, its factors are 1,13,31,403. For every factor, there is a corresponding negative factor, for 403, the negative factors -1, -13, -31, -403.
How to find the factors of 403?
There are various methods we apply to find the factors of any number. Few of them are listed here; multiplication method, division method, prime factors and prime factorization and factor tree method. These are explained in detail below, let’s learn !
Finding Factors Using Multiplication
Step 1: Find all pairs of numbers whose product is 403.
Step 2: All the pairs found represent the factors of 403.
403 is not a prime number. The pair of numbers whose product is 403 is;
1×403=403
13×31 = 403
The factors of 403 are 1,13,31,403.
Finding Factors by Division Method
Step 1: Start by dividing 403 with the smallest number, and check the remainders.
Step 2: 403 is not prime, therefore the divisors it has are 1,13,31,403. Any number that is further checked for divisibility leaves behind a remainder.
The factors of 403 are 1,13,31,403.
Prime factors and prime factorization
— 403 is not a prime number.
— The prime factorization of 403 is 13×31.
— Factors of 403 are 1,13,31,403.
Factor tree
— In this method, we make branches that extend from the number to express a number as the product of its factors.
— In the case of 403, only one branch will be extended, as the number is prime factorized as 13×31. 31 is a prime number and cannot be factored further.
