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 101,240,321, 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 | 101,240,321 | |
| -1 | -101,240,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,240,321.
Example:
1 x 101,240,321 = 101,240,321
and
-1 x -101,240,321 = 101,240,321
Notice both answers equal 101,240,321
With that explanation out of the way, let's continue. Next, we take the number 101,240,321 and divide it by 2:
101,240,321 ÷ 2 = 50,620,160.5
If the quotient is a whole number, then 2 and 50,620,160.5 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 | 101,240,321 | |
| -1 | -101,240,321 |
Now, we try dividing 101,240,321 by 3:
101,240,321 ÷ 3 = 33,746,773.6667
If the quotient is a whole number, then 3 and 33,746,773.6667 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 | 101,240,321 | |
| -1 | -101,240,321 |
Let's try dividing by 4:
101,240,321 ÷ 4 = 25,310,080.25
If the quotient is a whole number, then 4 and 25,310,080.25 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 | 101,240,321 | |
| -1 | 101,240,321 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 49 | 91 | 119 | 221 | 637 | 833 | 1,547 | 9,349 | 10,829 | 65,443 | 121,537 | 158,933 | 458,101 | 850,759 | 1,112,531 | 2,066,129 | 5,955,313 | 7,787,717 | 14,462,903 | 101,240,321 |
| -1 | -7 | -13 | -17 | -49 | -91 | -119 | -221 | -637 | -833 | -1,547 | -9,349 | -10,829 | -65,443 | -121,537 | -158,933 | -458,101 | -850,759 | -1,112,531 | -2,066,129 | -5,955,313 | -7,787,717 | -14,462,903 | -101,240,321 |
