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 3,575,143, 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 | 3,575,143 | |
| -1 | -3,575,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,575,143.
Example:
1 x 3,575,143 = 3,575,143
and
-1 x -3,575,143 = 3,575,143
Notice both answers equal 3,575,143
With that explanation out of the way, let's continue. Next, we take the number 3,575,143 and divide it by 2:
3,575,143 ÷ 2 = 1,787,571.5
If the quotient is a whole number, then 2 and 1,787,571.5 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 | 3,575,143 | |
| -1 | -3,575,143 |
Now, we try dividing 3,575,143 by 3:
3,575,143 ÷ 3 = 1,191,714.3333
If the quotient is a whole number, then 3 and 1,191,714.3333 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 | 3,575,143 | |
| -1 | -3,575,143 |
Let's try dividing by 4:
3,575,143 ÷ 4 = 893,785.75
If the quotient is a whole number, then 4 and 893,785.75 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 | 3,575,143 | |
| -1 | 3,575,143 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 23 | 143 | 253 | 299 | 1,087 | 3,289 | 11,957 | 14,131 | 25,001 | 155,441 | 275,011 | 325,013 | 3,575,143 |
| -1 | -11 | -13 | -23 | -143 | -253 | -299 | -1,087 | -3,289 | -11,957 | -14,131 | -25,001 | -155,441 | -275,011 | -325,013 | -3,575,143 |
