What is a factor in math ?
Factors are the numbers you multiply together to get another number. For example, the factors of 15 are 3 and 5 because 3 × 5 = 15.
The factors of a number can be positive or negative, but they cannot be zero.
The factors of a number can be used to find out if the number is prime or not.
A prime number is a number that has only two factors: itself and 1. For example, the number 7 is prime because its only factors are 7 and 1.
List all of the factors of 242 ?
To calculate the factors of 242 , you can use the division method.
1. Begin by dividing 242 by the smallest possible number, which is 2.
2. If the division is even, then 2 is a factor of 242.
3. Continue dividing 242 by larger numbers until you find an odd number that does not divide evenly into 242 .
4. The numbers that divide evenly into 242 are the factors of 242 .
Now let us find how to calculate all the factors of Two hundred forty-two :
242 ÷ 1 = 242
242 ÷ 2 = 121
242 ÷ 11 = 22
242 ÷ 22 = 11
242 ÷ 121 = 2
242 ÷ 242 = 1
As you can see, the factors of 242 are 1 , 2 , 11 , 22 , 121 and 242 .

Prime Factorisation of 242
There are a few different methods that can be used to calculate the prime factorization of a number. Two of the most common methods are listed below.
1) Use a factor tree :
1. Take the number you want to find the prime factorization of and write it at the top of the page
2. Find the smallest number that goes into the number you are finding the prime factorization of evenly and write it next to the number you are finding the prime factorization of
3. Draw a line under the number you just wrote and the number you are finding the prime factorization of
4. Repeat step 2 with the number you just wrote until that number can no longer be divided evenly
5. The numbers written on the lines will be the prime factors of the number you started with
For example, to calculate the prime factorization of 242 using a factor tree, we would start by writing 242 on a piece of paper. Then, we would draw a line under it and begin finding factors.
The final prime factorization of 242 would be 2 x 11 x 11.
2) Use a factorization method :
There are a few different factorization methods that can be used to calculate the prime factorization of a number.
One common method is to start by dividing the number by the smallest prime number that will divide evenly into it.
Then, continue dividing the number by successively larger prime numbers until the number has been fully factorised.
For example, to calculate the prime factorization of 242 using this method, we keep dividing until it gives a non-zero remainder.
242 ÷ 2 = 121
121 ÷ 11 = 11
11 ÷ 11 = 1
So the prime factors of 242 are 2 x 11 x 11.
