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 73,616,719, 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 | 73,616,719 | |
| -1 | -73,616,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,616,719.
Example:
1 x 73,616,719 = 73,616,719
and
-1 x -73,616,719 = 73,616,719
Notice both answers equal 73,616,719
With that explanation out of the way, let's continue. Next, we take the number 73,616,719 and divide it by 2:
73,616,719 ÷ 2 = 36,808,359.5
If the quotient is a whole number, then 2 and 36,808,359.5 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 | 73,616,719 | |
| -1 | -73,616,719 |
Now, we try dividing 73,616,719 by 3:
73,616,719 ÷ 3 = 24,538,906.3333
If the quotient is a whole number, then 3 and 24,538,906.3333 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 | 73,616,719 | |
| -1 | -73,616,719 |
Let's try dividing by 4:
73,616,719 ÷ 4 = 18,404,179.75
If the quotient is a whole number, then 4 and 18,404,179.75 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 | 73,616,719 | |
| -1 | 73,616,719 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 67 | 649 | 737 | 1,693 | 3,953 | 18,623 | 43,483 | 99,887 | 113,431 | 1,098,757 | 1,247,741 | 6,692,429 | 73,616,719 |
| -1 | -11 | -59 | -67 | -649 | -737 | -1,693 | -3,953 | -18,623 | -43,483 | -99,887 | -113,431 | -1,098,757 | -1,247,741 | -6,692,429 | -73,616,719 |
