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 716,562,055, 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 | 716,562,055 | |
| -1 | -716,562,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 716,562,055.
Example:
1 x 716,562,055 = 716,562,055
and
-1 x -716,562,055 = 716,562,055
Notice both answers equal 716,562,055
With that explanation out of the way, let's continue. Next, we take the number 716,562,055 and divide it by 2:
716,562,055 ÷ 2 = 358,281,027.5
If the quotient is a whole number, then 2 and 358,281,027.5 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 | 716,562,055 | |
| -1 | -716,562,055 |
Now, we try dividing 716,562,055 by 3:
716,562,055 ÷ 3 = 238,854,018.3333
If the quotient is a whole number, then 3 and 238,854,018.3333 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 | 716,562,055 | |
| -1 | -716,562,055 |
Let's try dividing by 4:
716,562,055 ÷ 4 = 179,140,513.75
If the quotient is a whole number, then 4 and 179,140,513.75 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 | 716,562,055 | |
| -1 | 716,562,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 1,705 | 420,271 | 2,101,355 | 4,622,981 | 13,028,401 | 23,114,905 | 65,142,005 | 143,312,411 | 716,562,055 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -1,705 | -420,271 | -2,101,355 | -4,622,981 | -13,028,401 | -23,114,905 | -65,142,005 | -143,312,411 | -716,562,055 |
