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 103,210,637, 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 | 103,210,637 | |
| -1 | -103,210,637 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,210,637.
Example:
1 x 103,210,637 = 103,210,637
and
-1 x -103,210,637 = 103,210,637
Notice both answers equal 103,210,637
With that explanation out of the way, let's continue. Next, we take the number 103,210,637 and divide it by 2:
103,210,637 ÷ 2 = 51,605,318.5
If the quotient is a whole number, then 2 and 51,605,318.5 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 | 103,210,637 | |
| -1 | -103,210,637 |
Now, we try dividing 103,210,637 by 3:
103,210,637 ÷ 3 = 34,403,545.6667
If the quotient is a whole number, then 3 and 34,403,545.6667 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 | 103,210,637 | |
| -1 | -103,210,637 |
Let's try dividing by 4:
103,210,637 ÷ 4 = 25,802,659.25
If the quotient is a whole number, then 4 and 25,802,659.25 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 | 103,210,637 | |
| -1 | 103,210,637 |
If you did it right, you will end up with this table:
| 1 | 23 | 47 | 307 | 311 | 1,081 | 7,061 | 7,153 | 14,429 | 14,617 | 95,477 | 331,867 | 336,191 | 2,195,971 | 4,487,419 | 103,210,637 |
| -1 | -23 | -47 | -307 | -311 | -1,081 | -7,061 | -7,153 | -14,429 | -14,617 | -95,477 | -331,867 | -336,191 | -2,195,971 | -4,487,419 | -103,210,637 |
