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 5,854,147, 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 | 5,854,147 | |
| -1 | -5,854,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,854,147.
Example:
1 x 5,854,147 = 5,854,147
and
-1 x -5,854,147 = 5,854,147
Notice both answers equal 5,854,147
With that explanation out of the way, let's continue. Next, we take the number 5,854,147 and divide it by 2:
5,854,147 ÷ 2 = 2,927,073.5
If the quotient is a whole number, then 2 and 2,927,073.5 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 | 5,854,147 | |
| -1 | -5,854,147 |
Now, we try dividing 5,854,147 by 3:
5,854,147 ÷ 3 = 1,951,382.3333
If the quotient is a whole number, then 3 and 1,951,382.3333 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 | 5,854,147 | |
| -1 | -5,854,147 |
Let's try dividing by 4:
5,854,147 ÷ 4 = 1,463,536.75
If the quotient is a whole number, then 4 and 1,463,536.75 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 | 5,854,147 | |
| -1 | 5,854,147 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 137 | 173 | 247 | 1,781 | 2,249 | 2,603 | 3,287 | 23,701 | 33,839 | 42,731 | 308,113 | 450,319 | 5,854,147 |
| -1 | -13 | -19 | -137 | -173 | -247 | -1,781 | -2,249 | -2,603 | -3,287 | -23,701 | -33,839 | -42,731 | -308,113 | -450,319 | -5,854,147 |
