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 265,061,363, 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 | 265,061,363 | |
| -1 | -265,061,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,061,363.
Example:
1 x 265,061,363 = 265,061,363
and
-1 x -265,061,363 = 265,061,363
Notice both answers equal 265,061,363
With that explanation out of the way, let's continue. Next, we take the number 265,061,363 and divide it by 2:
265,061,363 ÷ 2 = 132,530,681.5
If the quotient is a whole number, then 2 and 132,530,681.5 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 | 265,061,363 | |
| -1 | -265,061,363 |
Now, we try dividing 265,061,363 by 3:
265,061,363 ÷ 3 = 88,353,787.6667
If the quotient is a whole number, then 3 and 88,353,787.6667 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 | 265,061,363 | |
| -1 | -265,061,363 |
Let's try dividing by 4:
265,061,363 ÷ 4 = 66,265,340.75
If the quotient is a whole number, then 4 and 66,265,340.75 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 | 265,061,363 | |
| -1 | 265,061,363 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 107 | 203 | 749 | 3,103 | 12,203 | 21,721 | 85,421 | 353,887 | 1,305,721 | 2,477,209 | 9,140,047 | 37,865,909 | 265,061,363 |
| -1 | -7 | -29 | -107 | -203 | -749 | -3,103 | -12,203 | -21,721 | -85,421 | -353,887 | -1,305,721 | -2,477,209 | -9,140,047 | -37,865,909 | -265,061,363 |
