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 2890 ?
To calculate the factors of 2890 , you can use the division method.
1. Begin by dividing 2890 by the smallest possible number, which is 2.
2. If the division is even, then 2 is a factor of 2890.
3. Continue dividing 2890 by larger numbers until you find an odd number that does not divide evenly into 2890 .
4. The numbers that divide evenly into 2890 are the factors of 2890 .
Now let us find how to calculate all the factors of Two thousand eight hundred ninety :
2890 ÷ 1 = 2890
2890 ÷ 2 = 1445
2890 ÷ 5 = 578
2890 ÷ 10 = 289
2890 ÷ 17 = 170
2890 ÷ 34 = 85
2890 ÷ 85 = 34
2890 ÷ 170 = 17
2890 ÷ 289 = 10
2890 ÷ 578 = 5
2890 ÷ 1445 = 2
2890 ÷ 2890 = 1
As you can see, the factors of 2890 are 1 , 2 , 5 , 10 , 17 , 34 , 85 , 170 , 289 , 578 , 1445 and 2890 .

Prime Factorisation of 2890
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 2890 using a factor tree, we would start by writing 2890 on a piece of paper. Then, we would draw a line under it and begin finding factors.
The final prime factorization of 2890 would be 2 x 5 x 17 x 17.
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 2890 using this method, we keep dividing until it gives a non-zero remainder.
2890 ÷ 2 = 1445
1445 ÷ 5 = 289
289 ÷ 17 = 17
17 ÷ 17 = 1
So the prime factors of 2890 are 2 x 5 x 17 x 17.
