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 657,413,365, 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 | 657,413,365 | |
| -1 | -657,413,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 657,413,365.
Example:
1 x 657,413,365 = 657,413,365
and
-1 x -657,413,365 = 657,413,365
Notice both answers equal 657,413,365
With that explanation out of the way, let's continue. Next, we take the number 657,413,365 and divide it by 2:
657,413,365 ÷ 2 = 328,706,682.5
If the quotient is a whole number, then 2 and 328,706,682.5 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 | 657,413,365 | |
| -1 | -657,413,365 |
Now, we try dividing 657,413,365 by 3:
657,413,365 ÷ 3 = 219,137,788.3333
If the quotient is a whole number, then 3 and 219,137,788.3333 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 | 657,413,365 | |
| -1 | -657,413,365 |
Let's try dividing by 4:
657,413,365 ÷ 4 = 164,353,341.25
If the quotient is a whole number, then 4 and 164,353,341.25 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 | 657,413,365 | |
| -1 | 657,413,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 359 | 1,795 | 2,513 | 12,565 | 52,321 | 261,605 | 366,247 | 1,831,235 | 18,783,239 | 93,916,195 | 131,482,673 | 657,413,365 |
| -1 | -5 | -7 | -35 | -359 | -1,795 | -2,513 | -12,565 | -52,321 | -261,605 | -366,247 | -1,831,235 | -18,783,239 | -93,916,195 | -131,482,673 | -657,413,365 |
