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 265,246,345, 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 | 265,246,345 | |
| -1 | -265,246,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,246,345.
Example:
1 x 265,246,345 = 265,246,345
and
-1 x -265,246,345 = 265,246,345
Notice both answers equal 265,246,345
With that explanation out of the way, let's continue. Next, we take the number 265,246,345 and divide it by 2:
265,246,345 ÷ 2 = 132,623,172.5
If the quotient is a whole number, then 2 and 132,623,172.5 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 | 265,246,345 | |
| -1 | -265,246,345 |
Now, we try dividing 265,246,345 by 3:
265,246,345 ÷ 3 = 88,415,448.3333
If the quotient is a whole number, then 3 and 88,415,448.3333 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 | 265,246,345 | |
| -1 | -265,246,345 |
Let's try dividing by 4:
265,246,345 ÷ 4 = 66,311,586.25
If the quotient is a whole number, then 4 and 66,311,586.25 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 | 265,246,345 | |
| -1 | 265,246,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 455 | 845 | 1,183 | 5,915 | 44,843 | 224,215 | 313,901 | 582,959 | 1,569,505 | 2,914,795 | 4,080,713 | 7,578,467 | 20,403,565 | 37,892,335 | 53,049,269 | 265,246,345 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -455 | -845 | -1,183 | -5,915 | -44,843 | -224,215 | -313,901 | -582,959 | -1,569,505 | -2,914,795 | -4,080,713 | -7,578,467 | -20,403,565 | -37,892,335 | -53,049,269 | -265,246,345 |
