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 260,630,353, 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 | 260,630,353 | |
| -1 | -260,630,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,630,353.
Example:
1 x 260,630,353 = 260,630,353
and
-1 x -260,630,353 = 260,630,353
Notice both answers equal 260,630,353
With that explanation out of the way, let's continue. Next, we take the number 260,630,353 and divide it by 2:
260,630,353 ÷ 2 = 130,315,176.5
If the quotient is a whole number, then 2 and 130,315,176.5 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 | 260,630,353 | |
| -1 | -260,630,353 |
Now, we try dividing 260,630,353 by 3:
260,630,353 ÷ 3 = 86,876,784.3333
If the quotient is a whole number, then 3 and 86,876,784.3333 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 | 260,630,353 | |
| -1 | -260,630,353 |
Let's try dividing by 4:
260,630,353 ÷ 4 = 65,157,588.25
If the quotient is a whole number, then 4 and 65,157,588.25 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 | 260,630,353 | |
| -1 | 260,630,353 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 149 | 817 | 2,141 | 2,831 | 6,407 | 40,679 | 92,063 | 121,733 | 319,009 | 1,749,197 | 6,061,171 | 13,717,387 | 260,630,353 |
| -1 | -19 | -43 | -149 | -817 | -2,141 | -2,831 | -6,407 | -40,679 | -92,063 | -121,733 | -319,009 | -1,749,197 | -6,061,171 | -13,717,387 | -260,630,353 |
