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 13,464,275, 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 | 13,464,275 | |
| -1 | -13,464,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,464,275.
Example:
1 x 13,464,275 = 13,464,275
and
-1 x -13,464,275 = 13,464,275
Notice both answers equal 13,464,275
With that explanation out of the way, let's continue. Next, we take the number 13,464,275 and divide it by 2:
13,464,275 ÷ 2 = 6,732,137.5
If the quotient is a whole number, then 2 and 6,732,137.5 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 | 13,464,275 | |
| -1 | -13,464,275 |
Now, we try dividing 13,464,275 by 3:
13,464,275 ÷ 3 = 4,488,091.6667
If the quotient is a whole number, then 3 and 4,488,091.6667 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 | 13,464,275 | |
| -1 | -13,464,275 |
Let's try dividing by 4:
13,464,275 ÷ 4 = 3,366,068.75
If the quotient is a whole number, then 4 and 3,366,068.75 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 | 13,464,275 | |
| -1 | 13,464,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 4,451 | 22,255 | 48,961 | 111,275 | 244,805 | 538,571 | 1,224,025 | 2,692,855 | 13,464,275 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -4,451 | -22,255 | -48,961 | -111,275 | -244,805 | -538,571 | -1,224,025 | -2,692,855 | -13,464,275 |
