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 10,103,725, 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 | 10,103,725 | |
| -1 | -10,103,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,103,725.
Example:
1 x 10,103,725 = 10,103,725
and
-1 x -10,103,725 = 10,103,725
Notice both answers equal 10,103,725
With that explanation out of the way, let's continue. Next, we take the number 10,103,725 and divide it by 2:
10,103,725 ÷ 2 = 5,051,862.5
If the quotient is a whole number, then 2 and 5,051,862.5 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 | 10,103,725 | |
| -1 | -10,103,725 |
Now, we try dividing 10,103,725 by 3:
10,103,725 ÷ 3 = 3,367,908.3333
If the quotient is a whole number, then 3 and 3,367,908.3333 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 | 10,103,725 | |
| -1 | -10,103,725 |
Let's try dividing by 4:
10,103,725 ÷ 4 = 2,525,931.25
If the quotient is a whole number, then 4 and 2,525,931.25 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 | 10,103,725 | |
| -1 | 10,103,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 89 | 95 | 239 | 445 | 475 | 1,195 | 1,691 | 2,225 | 4,541 | 5,975 | 8,455 | 21,271 | 22,705 | 42,275 | 106,355 | 113,525 | 404,149 | 531,775 | 2,020,745 | 10,103,725 |
| -1 | -5 | -19 | -25 | -89 | -95 | -239 | -445 | -475 | -1,195 | -1,691 | -2,225 | -4,541 | -5,975 | -8,455 | -21,271 | -22,705 | -42,275 | -106,355 | -113,525 | -404,149 | -531,775 | -2,020,745 | -10,103,725 |
