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 10,498,787, 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 | 10,498,787 | |
| -1 | -10,498,787 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,498,787.
Example:
1 x 10,498,787 = 10,498,787
and
-1 x -10,498,787 = 10,498,787
Notice both answers equal 10,498,787
With that explanation out of the way, let's continue. Next, we take the number 10,498,787 and divide it by 2:
10,498,787 ÷ 2 = 5,249,393.5
If the quotient is a whole number, then 2 and 5,249,393.5 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 | 10,498,787 | |
| -1 | -10,498,787 |
Now, we try dividing 10,498,787 by 3:
10,498,787 ÷ 3 = 3,499,595.6667
If the quotient is a whole number, then 3 and 3,499,595.6667 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 | 10,498,787 | |
| -1 | -10,498,787 |
Let's try dividing by 4:
10,498,787 ÷ 4 = 2,624,696.75
If the quotient is a whole number, then 4 and 2,624,696.75 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 | 10,498,787 | |
| -1 | 10,498,787 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 37 | 73 | 169 | 299 | 481 | 851 | 949 | 1,679 | 2,701 | 3,887 | 6,253 | 11,063 | 12,337 | 21,827 | 35,113 | 62,123 | 143,819 | 283,751 | 456,469 | 807,599 | 10,498,787 |
| -1 | -13 | -23 | -37 | -73 | -169 | -299 | -481 | -851 | -949 | -1,679 | -2,701 | -3,887 | -6,253 | -11,063 | -12,337 | -21,827 | -35,113 | -62,123 | -143,819 | -283,751 | -456,469 | -807,599 | -10,498,787 |
