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 103,025,429, 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 | 103,025,429 | |
| -1 | -103,025,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,025,429.
Example:
1 x 103,025,429 = 103,025,429
and
-1 x -103,025,429 = 103,025,429
Notice both answers equal 103,025,429
With that explanation out of the way, let's continue. Next, we take the number 103,025,429 and divide it by 2:
103,025,429 ÷ 2 = 51,512,714.5
If the quotient is a whole number, then 2 and 51,512,714.5 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 | 103,025,429 | |
| -1 | -103,025,429 |
Now, we try dividing 103,025,429 by 3:
103,025,429 ÷ 3 = 34,341,809.6667
If the quotient is a whole number, then 3 and 34,341,809.6667 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 | 103,025,429 | |
| -1 | -103,025,429 |
Let's try dividing by 4:
103,025,429 ÷ 4 = 25,756,357.25
If the quotient is a whole number, then 4 and 25,756,357.25 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 | 103,025,429 | |
| -1 | 103,025,429 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 29 | 247 | 361 | 377 | 551 | 757 | 4,693 | 7,163 | 9,841 | 10,469 | 14,383 | 21,953 | 136,097 | 186,979 | 273,277 | 285,389 | 417,107 | 3,552,601 | 5,422,391 | 7,925,033 | 103,025,429 |
| -1 | -13 | -19 | -29 | -247 | -361 | -377 | -551 | -757 | -4,693 | -7,163 | -9,841 | -10,469 | -14,383 | -21,953 | -136,097 | -186,979 | -273,277 | -285,389 | -417,107 | -3,552,601 | -5,422,391 | -7,925,033 | -103,025,429 |
