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 73,673,743, 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 | 73,673,743 | |
| -1 | -73,673,743 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,673,743.
Example:
1 x 73,673,743 = 73,673,743
and
-1 x -73,673,743 = 73,673,743
Notice both answers equal 73,673,743
With that explanation out of the way, let's continue. Next, we take the number 73,673,743 and divide it by 2:
73,673,743 ÷ 2 = 36,836,871.5
If the quotient is a whole number, then 2 and 36,836,871.5 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 | 73,673,743 | |
| -1 | -73,673,743 |
Now, we try dividing 73,673,743 by 3:
73,673,743 ÷ 3 = 24,557,914.3333
If the quotient is a whole number, then 3 and 24,557,914.3333 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 | 73,673,743 | |
| -1 | -73,673,743 |
Let's try dividing by 4:
73,673,743 ÷ 4 = 18,418,435.75
If the quotient is a whole number, then 4 and 18,418,435.75 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 | 73,673,743 | |
| -1 | 73,673,743 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 101 | 143 | 1,111 | 1,313 | 5,101 | 14,443 | 56,111 | 66,313 | 515,201 | 729,443 | 5,667,211 | 6,697,613 | 73,673,743 |
| -1 | -11 | -13 | -101 | -143 | -1,111 | -1,313 | -5,101 | -14,443 | -56,111 | -66,313 | -515,201 | -729,443 | -5,667,211 | -6,697,613 | -73,673,743 |
