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 14,856,725, 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 | 14,856,725 | |
| -1 | -14,856,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,856,725.
Example:
1 x 14,856,725 = 14,856,725
and
-1 x -14,856,725 = 14,856,725
Notice both answers equal 14,856,725
With that explanation out of the way, let's continue. Next, we take the number 14,856,725 and divide it by 2:
14,856,725 ÷ 2 = 7,428,362.5
If the quotient is a whole number, then 2 and 7,428,362.5 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 | 14,856,725 | |
| -1 | -14,856,725 |
Now, we try dividing 14,856,725 by 3:
14,856,725 ÷ 3 = 4,952,241.6667
If the quotient is a whole number, then 3 and 4,952,241.6667 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 | 14,856,725 | |
| -1 | -14,856,725 |
Let's try dividing by 4:
14,856,725 ÷ 4 = 3,714,181.25
If the quotient is a whole number, then 4 and 3,714,181.25 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 | 14,856,725 | |
| -1 | 14,856,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 25 | 65 | 85 | 221 | 325 | 425 | 1,105 | 2,689 | 5,525 | 13,445 | 34,957 | 45,713 | 67,225 | 174,785 | 228,565 | 594,269 | 873,925 | 1,142,825 | 2,971,345 | 14,856,725 |
| -1 | -5 | -13 | -17 | -25 | -65 | -85 | -221 | -325 | -425 | -1,105 | -2,689 | -5,525 | -13,445 | -34,957 | -45,713 | -67,225 | -174,785 | -228,565 | -594,269 | -873,925 | -1,142,825 | -2,971,345 | -14,856,725 |
