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 35,868,625, 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 | 35,868,625 | |
| -1 | -35,868,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,868,625.
Example:
1 x 35,868,625 = 35,868,625
and
-1 x -35,868,625 = 35,868,625
Notice both answers equal 35,868,625
With that explanation out of the way, let's continue. Next, we take the number 35,868,625 and divide it by 2:
35,868,625 ÷ 2 = 17,934,312.5
If the quotient is a whole number, then 2 and 17,934,312.5 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 | 35,868,625 | |
| -1 | -35,868,625 |
Now, we try dividing 35,868,625 by 3:
35,868,625 ÷ 3 = 11,956,208.3333
If the quotient is a whole number, then 3 and 11,956,208.3333 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 | 35,868,625 | |
| -1 | -35,868,625 |
Let's try dividing by 4:
35,868,625 ÷ 4 = 8,967,156.25
If the quotient is a whole number, then 4 and 8,967,156.25 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 | 35,868,625 | |
| -1 | 35,868,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,625 | 22,073 | 110,365 | 286,949 | 551,825 | 1,434,745 | 2,759,125 | 7,173,725 | 35,868,625 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,625 | -22,073 | -110,365 | -286,949 | -551,825 | -1,434,745 | -2,759,125 | -7,173,725 | -35,868,625 |
