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 3,571,139, 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 | 3,571,139 | |
| -1 | -3,571,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,571,139.
Example:
1 x 3,571,139 = 3,571,139
and
-1 x -3,571,139 = 3,571,139
Notice both answers equal 3,571,139
With that explanation out of the way, let's continue. Next, we take the number 3,571,139 and divide it by 2:
3,571,139 ÷ 2 = 1,785,569.5
If the quotient is a whole number, then 2 and 1,785,569.5 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 | 3,571,139 | |
| -1 | -3,571,139 |
Now, we try dividing 3,571,139 by 3:
3,571,139 ÷ 3 = 1,190,379.6667
If the quotient is a whole number, then 3 and 1,190,379.6667 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 | 3,571,139 | |
| -1 | -3,571,139 |
Let's try dividing by 4:
3,571,139 ÷ 4 = 892,784.75
If the quotient is a whole number, then 4 and 892,784.75 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 | 3,571,139 | |
| -1 | 3,571,139 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 113 | 143 | 169 | 187 | 221 | 1,243 | 1,469 | 1,859 | 1,921 | 2,431 | 2,873 | 16,159 | 19,097 | 21,131 | 24,973 | 31,603 | 210,067 | 274,703 | 324,649 | 3,571,139 |
| -1 | -11 | -13 | -17 | -113 | -143 | -169 | -187 | -221 | -1,243 | -1,469 | -1,859 | -1,921 | -2,431 | -2,873 | -16,159 | -19,097 | -21,131 | -24,973 | -31,603 | -210,067 | -274,703 | -324,649 | -3,571,139 |
