Factors of 343
Factors are the ‘building blocks’ of a number. They are the numbers that can be multiplied together to reach the number you started with. 343 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 343?
Factors are whole numbers that, when multiplied, the product is equal to 343.
343 is not a prime number, its factors are 1,7,49 and 343. For every factor, there is a corresponding negative factor, for 343, the negative factors -1, -7, -49 and -343.
How to find the factors of 343?
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 343.
Step 2: All the pairs found represent the factors of 343.
343 is not a prime number. The pair of numbers whose product is 343 is;
1×343=343
7×49 = 343
The factors of 343 are 1, 7, 49 and 343.
Finding Factors by Division Method
Step 1: Start by dividing 343 with the smallest number, and check the remainders.
Step 2: 343 is not prime, therefore the divisors it has are 1, 7, 49 and 343. Any number that is further checked for divisibility leaves behind a remainder.
The factors of 343 are 1, 7, 49 and 343.
Prime factors and prime factorization
— 343 is not a prime number.
— The prime factorization of 343 is 7×7×7 = 343.
— Factors of 343 are 1, 7, 49 and 343.
Factor tree
— In this method, we make branches that extend from the number to express a number as the product of its factors.
— In case of 343, only three branches will be extended as the number is prime factorized as 40 times 7 and 49 is factorized into 7 times 7. 7 is a prime number and cannot be factored further. The factorization ends here.
