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 103,525,165, 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 | 103,525,165 | |
| -1 | -103,525,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,525,165.
Example:
1 x 103,525,165 = 103,525,165
and
-1 x -103,525,165 = 103,525,165
Notice both answers equal 103,525,165
With that explanation out of the way, let's continue. Next, we take the number 103,525,165 and divide it by 2:
103,525,165 ÷ 2 = 51,762,582.5
If the quotient is a whole number, then 2 and 51,762,582.5 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 | 103,525,165 | |
| -1 | -103,525,165 |
Now, we try dividing 103,525,165 by 3:
103,525,165 ÷ 3 = 34,508,388.3333
If the quotient is a whole number, then 3 and 34,508,388.3333 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 | 103,525,165 | |
| -1 | -103,525,165 |
Let's try dividing by 4:
103,525,165 ÷ 4 = 25,881,291.25
If the quotient is a whole number, then 4 and 25,881,291.25 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 | 103,525,165 | |
| -1 | 103,525,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 241 | 265 | 1,205 | 1,621 | 8,105 | 12,773 | 63,865 | 85,913 | 390,661 | 429,565 | 1,953,305 | 20,705,033 | 103,525,165 |
| -1 | -5 | -53 | -241 | -265 | -1,205 | -1,621 | -8,105 | -12,773 | -63,865 | -85,913 | -390,661 | -429,565 | -1,953,305 | -20,705,033 | -103,525,165 |
