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 372,547,553, 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 | 372,547,553 | |
| -1 | -372,547,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 372,547,553.
Example:
1 x 372,547,553 = 372,547,553
and
-1 x -372,547,553 = 372,547,553
Notice both answers equal 372,547,553
With that explanation out of the way, let's continue. Next, we take the number 372,547,553 and divide it by 2:
372,547,553 ÷ 2 = 186,273,776.5
If the quotient is a whole number, then 2 and 186,273,776.5 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 | 372,547,553 | |
| -1 | -372,547,553 |
Now, we try dividing 372,547,553 by 3:
372,547,553 ÷ 3 = 124,182,517.6667
If the quotient is a whole number, then 3 and 124,182,517.6667 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 | 372,547,553 | |
| -1 | -372,547,553 |
Let's try dividing by 4:
372,547,553 ÷ 4 = 93,136,888.25
If the quotient is a whole number, then 4 and 93,136,888.25 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 | 372,547,553 | |
| -1 | 372,547,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 113 | 217 | 791 | 3,503 | 15,193 | 24,521 | 106,351 | 470,983 | 1,716,809 | 3,296,881 | 12,017,663 | 53,221,079 | 372,547,553 |
| -1 | -7 | -31 | -113 | -217 | -791 | -3,503 | -15,193 | -24,521 | -106,351 | -470,983 | -1,716,809 | -3,296,881 | -12,017,663 | -53,221,079 | -372,547,553 |
