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 67,383,173, 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 | 67,383,173 | |
| -1 | -67,383,173 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,383,173.
Example:
1 x 67,383,173 = 67,383,173
and
-1 x -67,383,173 = 67,383,173
Notice both answers equal 67,383,173
With that explanation out of the way, let's continue. Next, we take the number 67,383,173 and divide it by 2:
67,383,173 ÷ 2 = 33,691,586.5
If the quotient is a whole number, then 2 and 33,691,586.5 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 | 67,383,173 | |
| -1 | -67,383,173 |
Now, we try dividing 67,383,173 by 3:
67,383,173 ÷ 3 = 22,461,057.6667
If the quotient is a whole number, then 3 and 22,461,057.6667 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 | 67,383,173 | |
| -1 | -67,383,173 |
Let's try dividing by 4:
67,383,173 ÷ 4 = 16,845,793.25
If the quotient is a whole number, then 4 and 16,845,793.25 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 | 67,383,173 | |
| -1 | 67,383,173 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 67 | 143 | 169 | 541 | 737 | 871 | 1,859 | 5,951 | 7,033 | 9,581 | 11,323 | 36,247 | 77,363 | 91,429 | 124,553 | 398,717 | 471,211 | 1,005,719 | 5,183,321 | 6,125,743 | 67,383,173 |
| -1 | -11 | -13 | -67 | -143 | -169 | -541 | -737 | -871 | -1,859 | -5,951 | -7,033 | -9,581 | -11,323 | -36,247 | -77,363 | -91,429 | -124,553 | -398,717 | -471,211 | -1,005,719 | -5,183,321 | -6,125,743 | -67,383,173 |
