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 7,452,731, 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 | 7,452,731 | |
| -1 | -7,452,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,452,731.
Example:
1 x 7,452,731 = 7,452,731
and
-1 x -7,452,731 = 7,452,731
Notice both answers equal 7,452,731
With that explanation out of the way, let's continue. Next, we take the number 7,452,731 and divide it by 2:
7,452,731 ÷ 2 = 3,726,365.5
If the quotient is a whole number, then 2 and 3,726,365.5 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 | 7,452,731 | |
| -1 | -7,452,731 |
Now, we try dividing 7,452,731 by 3:
7,452,731 ÷ 3 = 2,484,243.6667
If the quotient is a whole number, then 3 and 2,484,243.6667 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 | 7,452,731 | |
| -1 | -7,452,731 |
Let's try dividing by 4:
7,452,731 ÷ 4 = 1,863,182.75
If the quotient is a whole number, then 4 and 1,863,182.75 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 | 7,452,731 | |
| -1 | 7,452,731 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 143 | 169 | 209 | 211 | 247 | 1,859 | 2,321 | 2,717 | 2,743 | 3,211 | 4,009 | 30,173 | 35,321 | 35,659 | 44,099 | 52,117 | 392,249 | 573,287 | 677,521 | 7,452,731 |
| -1 | -11 | -13 | -19 | -143 | -169 | -209 | -211 | -247 | -1,859 | -2,321 | -2,717 | -2,743 | -3,211 | -4,009 | -30,173 | -35,321 | -35,659 | -44,099 | -52,117 | -392,249 | -573,287 | -677,521 | -7,452,731 |
