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 73,267,505, 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 | 73,267,505 | |
| -1 | -73,267,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,267,505.
Example:
1 x 73,267,505 = 73,267,505
and
-1 x -73,267,505 = 73,267,505
Notice both answers equal 73,267,505
With that explanation out of the way, let's continue. Next, we take the number 73,267,505 and divide it by 2:
73,267,505 ÷ 2 = 36,633,752.5
If the quotient is a whole number, then 2 and 36,633,752.5 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 | 73,267,505 | |
| -1 | -73,267,505 |
Now, we try dividing 73,267,505 by 3:
73,267,505 ÷ 3 = 24,422,501.6667
If the quotient is a whole number, then 3 and 24,422,501.6667 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 | 73,267,505 | |
| -1 | -73,267,505 |
Let's try dividing by 4:
73,267,505 ÷ 4 = 18,316,876.25
If the quotient is a whole number, then 4 and 18,316,876.25 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 | 73,267,505 | |
| -1 | 73,267,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 103 | 113 | 515 | 565 | 1,259 | 6,295 | 11,639 | 58,195 | 129,677 | 142,267 | 648,385 | 711,335 | 14,653,501 | 73,267,505 |
| -1 | -5 | -103 | -113 | -515 | -565 | -1,259 | -6,295 | -11,639 | -58,195 | -129,677 | -142,267 | -648,385 | -711,335 | -14,653,501 | -73,267,505 |
