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 265,470,359, 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 | 265,470,359 | |
| -1 | -265,470,359 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,470,359.
Example:
1 x 265,470,359 = 265,470,359
and
-1 x -265,470,359 = 265,470,359
Notice both answers equal 265,470,359
With that explanation out of the way, let's continue. Next, we take the number 265,470,359 and divide it by 2:
265,470,359 ÷ 2 = 132,735,179.5
If the quotient is a whole number, then 2 and 132,735,179.5 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 | 265,470,359 | |
| -1 | -265,470,359 |
Now, we try dividing 265,470,359 by 3:
265,470,359 ÷ 3 = 88,490,119.6667
If the quotient is a whole number, then 3 and 88,490,119.6667 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 | 265,470,359 | |
| -1 | -265,470,359 |
Let's try dividing by 4:
265,470,359 ÷ 4 = 66,367,589.75
If the quotient is a whole number, then 4 and 66,367,589.75 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 | 265,470,359 | |
| -1 | 265,470,359 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 263 | 1,841 | 2,893 | 13,109 | 20,251 | 91,763 | 144,199 | 1,009,393 | 3,447,667 | 24,133,669 | 37,924,337 | 265,470,359 |
| -1 | -7 | -11 | -77 | -263 | -1,841 | -2,893 | -13,109 | -20,251 | -91,763 | -144,199 | -1,009,393 | -3,447,667 | -24,133,669 | -37,924,337 | -265,470,359 |
