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 103,246,451, 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 | 103,246,451 | |
| -1 | -103,246,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,246,451.
Example:
1 x 103,246,451 = 103,246,451
and
-1 x -103,246,451 = 103,246,451
Notice both answers equal 103,246,451
With that explanation out of the way, let's continue. Next, we take the number 103,246,451 and divide it by 2:
103,246,451 ÷ 2 = 51,623,225.5
If the quotient is a whole number, then 2 and 51,623,225.5 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 | 103,246,451 | |
| -1 | -103,246,451 |
Now, we try dividing 103,246,451 by 3:
103,246,451 ÷ 3 = 34,415,483.6667
If the quotient is a whole number, then 3 and 34,415,483.6667 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 | 103,246,451 | |
| -1 | -103,246,451 |
Let's try dividing by 4:
103,246,451 ÷ 4 = 25,811,612.75
If the quotient is a whole number, then 4 and 25,811,612.75 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 | 103,246,451 | |
| -1 | 103,246,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 77 | 329 | 517 | 607 | 2,209 | 3,619 | 4,249 | 6,677 | 15,463 | 24,299 | 28,529 | 46,739 | 170,093 | 199,703 | 313,819 | 1,340,863 | 2,196,733 | 9,386,041 | 14,749,493 | 103,246,451 |
| -1 | -7 | -11 | -47 | -77 | -329 | -517 | -607 | -2,209 | -3,619 | -4,249 | -6,677 | -15,463 | -24,299 | -28,529 | -46,739 | -170,093 | -199,703 | -313,819 | -1,340,863 | -2,196,733 | -9,386,041 | -14,749,493 | -103,246,451 |
