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 610,212,355, 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 | 610,212,355 | |
| -1 | -610,212,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 610,212,355.
Example:
1 x 610,212,355 = 610,212,355
and
-1 x -610,212,355 = 610,212,355
Notice both answers equal 610,212,355
With that explanation out of the way, let's continue. Next, we take the number 610,212,355 and divide it by 2:
610,212,355 ÷ 2 = 305,106,177.5
If the quotient is a whole number, then 2 and 305,106,177.5 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 | 610,212,355 | |
| -1 | -610,212,355 |
Now, we try dividing 610,212,355 by 3:
610,212,355 ÷ 3 = 203,404,118.3333
If the quotient is a whole number, then 3 and 203,404,118.3333 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 | 610,212,355 | |
| -1 | -610,212,355 |
Let's try dividing by 4:
610,212,355 ÷ 4 = 152,553,088.75
If the quotient is a whole number, then 4 and 152,553,088.75 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 | 610,212,355 | |
| -1 | 610,212,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 821 | 3,457 | 4,105 | 17,285 | 35,303 | 148,651 | 176,515 | 743,255 | 2,838,197 | 14,190,985 | 122,042,471 | 610,212,355 |
| -1 | -5 | -43 | -215 | -821 | -3,457 | -4,105 | -17,285 | -35,303 | -148,651 | -176,515 | -743,255 | -2,838,197 | -14,190,985 | -122,042,471 | -610,212,355 |
