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 13,570,465, 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 | 13,570,465 | |
| -1 | -13,570,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,570,465.
Example:
1 x 13,570,465 = 13,570,465
and
-1 x -13,570,465 = 13,570,465
Notice both answers equal 13,570,465
With that explanation out of the way, let's continue. Next, we take the number 13,570,465 and divide it by 2:
13,570,465 ÷ 2 = 6,785,232.5
If the quotient is a whole number, then 2 and 6,785,232.5 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 | 13,570,465 | |
| -1 | -13,570,465 |
Now, we try dividing 13,570,465 by 3:
13,570,465 ÷ 3 = 4,523,488.3333
If the quotient is a whole number, then 3 and 4,523,488.3333 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 | 13,570,465 | |
| -1 | -13,570,465 |
Let's try dividing by 4:
13,570,465 ÷ 4 = 3,392,616.25
If the quotient is a whole number, then 4 and 3,392,616.25 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 | 13,570,465 | |
| -1 | 13,570,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 211 | 677 | 1,055 | 3,385 | 4,009 | 12,863 | 20,045 | 64,315 | 142,847 | 714,235 | 2,714,093 | 13,570,465 |
| -1 | -5 | -19 | -95 | -211 | -677 | -1,055 | -3,385 | -4,009 | -12,863 | -20,045 | -64,315 | -142,847 | -714,235 | -2,714,093 | -13,570,465 |
