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 7,310,555, 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 | 7,310,555 | |
| -1 | -7,310,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,310,555.
Example:
1 x 7,310,555 = 7,310,555
and
-1 x -7,310,555 = 7,310,555
Notice both answers equal 7,310,555
With that explanation out of the way, let's continue. Next, we take the number 7,310,555 and divide it by 2:
7,310,555 ÷ 2 = 3,655,277.5
If the quotient is a whole number, then 2 and 3,655,277.5 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 | 7,310,555 | |
| -1 | -7,310,555 |
Now, we try dividing 7,310,555 by 3:
7,310,555 ÷ 3 = 2,436,851.6667
If the quotient is a whole number, then 3 and 2,436,851.6667 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 | 7,310,555 | |
| -1 | -7,310,555 |
Let's try dividing by 4:
7,310,555 ÷ 4 = 1,827,638.75
If the quotient is a whole number, then 4 and 1,827,638.75 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 | 7,310,555 | |
| -1 | 7,310,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 53 | 245 | 265 | 371 | 563 | 1,855 | 2,597 | 2,815 | 3,941 | 12,985 | 19,705 | 27,587 | 29,839 | 137,935 | 149,195 | 208,873 | 1,044,365 | 1,462,111 | 7,310,555 |
| -1 | -5 | -7 | -35 | -49 | -53 | -245 | -265 | -371 | -563 | -1,855 | -2,597 | -2,815 | -3,941 | -12,985 | -19,705 | -27,587 | -29,839 | -137,935 | -149,195 | -208,873 | -1,044,365 | -1,462,111 | -7,310,555 |
