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 16,407,295, 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 | 16,407,295 | |
| -1 | -16,407,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,407,295.
Example:
1 x 16,407,295 = 16,407,295
and
-1 x -16,407,295 = 16,407,295
Notice both answers equal 16,407,295
With that explanation out of the way, let's continue. Next, we take the number 16,407,295 and divide it by 2:
16,407,295 ÷ 2 = 8,203,647.5
If the quotient is a whole number, then 2 and 8,203,647.5 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 | 16,407,295 | |
| -1 | -16,407,295 |
Now, we try dividing 16,407,295 by 3:
16,407,295 ÷ 3 = 5,469,098.3333
If the quotient is a whole number, then 3 and 5,469,098.3333 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 | 16,407,295 | |
| -1 | -16,407,295 |
Let's try dividing by 4:
16,407,295 ÷ 4 = 4,101,823.75
If the quotient is a whole number, then 4 and 4,101,823.75 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 | 16,407,295 | |
| -1 | 16,407,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 67 | 85 | 215 | 335 | 731 | 1,139 | 2,881 | 3,655 | 4,489 | 5,695 | 14,405 | 22,445 | 48,977 | 76,313 | 193,027 | 244,885 | 381,565 | 965,135 | 3,281,459 | 16,407,295 |
| -1 | -5 | -17 | -43 | -67 | -85 | -215 | -335 | -731 | -1,139 | -2,881 | -3,655 | -4,489 | -5,695 | -14,405 | -22,445 | -48,977 | -76,313 | -193,027 | -244,885 | -381,565 | -965,135 | -3,281,459 | -16,407,295 |
