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 16,069,963, 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 | 16,069,963 | |
| -1 | -16,069,963 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,069,963.
Example:
1 x 16,069,963 = 16,069,963
and
-1 x -16,069,963 = 16,069,963
Notice both answers equal 16,069,963
With that explanation out of the way, let's continue. Next, we take the number 16,069,963 and divide it by 2:
16,069,963 ÷ 2 = 8,034,981.5
If the quotient is a whole number, then 2 and 8,034,981.5 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 | 16,069,963 | |
| -1 | -16,069,963 |
Now, we try dividing 16,069,963 by 3:
16,069,963 ÷ 3 = 5,356,654.3333
If the quotient is a whole number, then 3 and 5,356,654.3333 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 | 16,069,963 | |
| -1 | -16,069,963 |
Let's try dividing by 4:
16,069,963 ÷ 4 = 4,017,490.75
If the quotient is a whole number, then 4 and 4,017,490.75 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 | 16,069,963 | |
| -1 | 16,069,963 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 137 | 959 | 1,289 | 1,781 | 9,023 | 12,467 | 16,757 | 117,299 | 176,593 | 1,236,151 | 2,295,709 | 16,069,963 |
| -1 | -7 | -13 | -91 | -137 | -959 | -1,289 | -1,781 | -9,023 | -12,467 | -16,757 | -117,299 | -176,593 | -1,236,151 | -2,295,709 | -16,069,963 |
