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 371,685,725, 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 | 371,685,725 | |
| -1 | -371,685,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 371,685,725.
Example:
1 x 371,685,725 = 371,685,725
and
-1 x -371,685,725 = 371,685,725
Notice both answers equal 371,685,725
With that explanation out of the way, let's continue. Next, we take the number 371,685,725 and divide it by 2:
371,685,725 ÷ 2 = 185,842,862.5
If the quotient is a whole number, then 2 and 185,842,862.5 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 | 371,685,725 | |
| -1 | -371,685,725 |
Now, we try dividing 371,685,725 by 3:
371,685,725 ÷ 3 = 123,895,241.6667
If the quotient is a whole number, then 3 and 123,895,241.6667 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 | 371,685,725 | |
| -1 | -371,685,725 |
Let's try dividing by 4:
371,685,725 ÷ 4 = 92,921,431.25
If the quotient is a whole number, then 4 and 92,921,431.25 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 | 371,685,725 | |
| -1 | 371,685,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 157 | 281 | 337 | 785 | 1,405 | 1,685 | 3,925 | 7,025 | 8,425 | 44,117 | 52,909 | 94,697 | 220,585 | 264,545 | 473,485 | 1,102,925 | 1,322,725 | 2,367,425 | 14,867,429 | 74,337,145 | 371,685,725 |
| -1 | -5 | -25 | -157 | -281 | -337 | -785 | -1,405 | -1,685 | -3,925 | -7,025 | -8,425 | -44,117 | -52,909 | -94,697 | -220,585 | -264,545 | -473,485 | -1,102,925 | -1,322,725 | -2,367,425 | -14,867,429 | -74,337,145 | -371,685,725 |
