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 374,440,115, 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 | 374,440,115 | |
| -1 | -374,440,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 374,440,115.
Example:
1 x 374,440,115 = 374,440,115
and
-1 x -374,440,115 = 374,440,115
Notice both answers equal 374,440,115
With that explanation out of the way, let's continue. Next, we take the number 374,440,115 and divide it by 2:
374,440,115 ÷ 2 = 187,220,057.5
If the quotient is a whole number, then 2 and 187,220,057.5 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 | 374,440,115 | |
| -1 | -374,440,115 |
Now, we try dividing 374,440,115 by 3:
374,440,115 ÷ 3 = 124,813,371.6667
If the quotient is a whole number, then 3 and 124,813,371.6667 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 | 374,440,115 | |
| -1 | -374,440,115 |
Let's try dividing by 4:
374,440,115 ÷ 4 = 93,610,028.75
If the quotient is a whole number, then 4 and 93,610,028.75 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 | 374,440,115 | |
| -1 | 374,440,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 49 | 115 | 161 | 245 | 805 | 1,127 | 5,635 | 66,449 | 332,245 | 465,143 | 1,528,327 | 2,325,715 | 3,256,001 | 7,641,635 | 10,698,289 | 16,280,005 | 53,491,445 | 74,888,023 | 374,440,115 |
| -1 | -5 | -7 | -23 | -35 | -49 | -115 | -161 | -245 | -805 | -1,127 | -5,635 | -66,449 | -332,245 | -465,143 | -1,528,327 | -2,325,715 | -3,256,001 | -7,641,635 | -10,698,289 | -16,280,005 | -53,491,445 | -74,888,023 | -374,440,115 |
