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 372,712,529, 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 | 372,712,529 | |
| -1 | -372,712,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 372,712,529.
Example:
1 x 372,712,529 = 372,712,529
and
-1 x -372,712,529 = 372,712,529
Notice both answers equal 372,712,529
With that explanation out of the way, let's continue. Next, we take the number 372,712,529 and divide it by 2:
372,712,529 ÷ 2 = 186,356,264.5
If the quotient is a whole number, then 2 and 186,356,264.5 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 | 372,712,529 | |
| -1 | -372,712,529 |
Now, we try dividing 372,712,529 by 3:
372,712,529 ÷ 3 = 124,237,509.6667
If the quotient is a whole number, then 3 and 124,237,509.6667 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 | 372,712,529 | |
| -1 | -372,712,529 |
Let's try dividing by 4:
372,712,529 ÷ 4 = 93,178,132.25
If the quotient is a whole number, then 4 and 93,178,132.25 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 | 372,712,529 | |
| -1 | 372,712,529 |
If you did it right, you will end up with this table:
| 1 | 7 | 109 | 193 | 763 | 1,351 | 2,531 | 17,717 | 21,037 | 147,259 | 275,879 | 488,483 | 1,931,153 | 3,419,381 | 53,244,647 | 372,712,529 |
| -1 | -7 | -109 | -193 | -763 | -1,351 | -2,531 | -17,717 | -21,037 | -147,259 | -275,879 | -488,483 | -1,931,153 | -3,419,381 | -53,244,647 | -372,712,529 |
