Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 2,358,223, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 2,358,223 | |
| -1 | -2,358,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,358,223.
Example:
1 x 2,358,223 = 2,358,223
and
-1 x -2,358,223 = 2,358,223
Notice both answers equal 2,358,223
With that explanation out of the way, let's continue. Next, we take the number 2,358,223 and divide it by 2:
2,358,223 ÷ 2 = 1,179,111.5
If the quotient is a whole number, then 2 and 1,179,111.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,358,223 | |
| -1 | -2,358,223 |
Now, we try dividing 2,358,223 by 3:
2,358,223 ÷ 3 = 786,074.3333
If the quotient is a whole number, then 3 and 786,074.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,358,223 | |
| -1 | -2,358,223 |
Let's try dividing by 4:
2,358,223 ÷ 4 = 589,555.75
If the quotient is a whole number, then 4 and 589,555.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,358,223 | |
| -1 | 2,358,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 49 | 119 | 133 | 149 | 323 | 833 | 931 | 1,043 | 2,261 | 2,533 | 2,831 | 7,301 | 15,827 | 17,731 | 19,817 | 48,127 | 124,117 | 138,719 | 336,889 | 2,358,223 |
| -1 | -7 | -17 | -19 | -49 | -119 | -133 | -149 | -323 | -833 | -931 | -1,043 | -2,261 | -2,533 | -2,831 | -7,301 | -15,827 | -17,731 | -19,817 | -48,127 | -124,117 | -138,719 | -336,889 | -2,358,223 |
