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 371,702,185, 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 | 371,702,185 | |
| -1 | -371,702,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 371,702,185.
Example:
1 x 371,702,185 = 371,702,185
and
-1 x -371,702,185 = 371,702,185
Notice both answers equal 371,702,185
With that explanation out of the way, let's continue. Next, we take the number 371,702,185 and divide it by 2:
371,702,185 ÷ 2 = 185,851,092.5
If the quotient is a whole number, then 2 and 185,851,092.5 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 | 371,702,185 | |
| -1 | -371,702,185 |
Now, we try dividing 371,702,185 by 3:
371,702,185 ÷ 3 = 123,900,728.3333
If the quotient is a whole number, then 3 and 123,900,728.3333 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 | 371,702,185 | |
| -1 | -371,702,185 |
Let's try dividing by 4:
371,702,185 ÷ 4 = 92,925,546.25
If the quotient is a whole number, then 4 and 92,925,546.25 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 | 371,702,185 | |
| -1 | 371,702,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 859 | 2,339 | 4,295 | 11,695 | 31,783 | 86,543 | 158,915 | 432,715 | 2,009,201 | 10,046,005 | 74,340,437 | 371,702,185 |
| -1 | -5 | -37 | -185 | -859 | -2,339 | -4,295 | -11,695 | -31,783 | -86,543 | -158,915 | -432,715 | -2,009,201 | -10,046,005 | -74,340,437 | -371,702,185 |
