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 10,045,451, 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 | 10,045,451 | |
| -1 | -10,045,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,045,451.
Example:
1 x 10,045,451 = 10,045,451
and
-1 x -10,045,451 = 10,045,451
Notice both answers equal 10,045,451
With that explanation out of the way, let's continue. Next, we take the number 10,045,451 and divide it by 2:
10,045,451 ÷ 2 = 5,022,725.5
If the quotient is a whole number, then 2 and 5,022,725.5 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 | 10,045,451 | |
| -1 | -10,045,451 |
Now, we try dividing 10,045,451 by 3:
10,045,451 ÷ 3 = 3,348,483.6667
If the quotient is a whole number, then 3 and 3,348,483.6667 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 | 10,045,451 | |
| -1 | -10,045,451 |
Let's try dividing by 4:
10,045,451 ÷ 4 = 2,511,362.75
If the quotient is a whole number, then 4 and 2,511,362.75 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 | 10,045,451 | |
| -1 | 10,045,451 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 47 | 401 | 533 | 611 | 1,927 | 5,213 | 16,441 | 18,847 | 25,051 | 213,733 | 245,011 | 772,727 | 10,045,451 |
| -1 | -13 | -41 | -47 | -401 | -533 | -611 | -1,927 | -5,213 | -16,441 | -18,847 | -25,051 | -213,733 | -245,011 | -772,727 | -10,045,451 |
