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 35,612,815, 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 | 35,612,815 | |
| -1 | -35,612,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,612,815.
Example:
1 x 35,612,815 = 35,612,815
and
-1 x -35,612,815 = 35,612,815
Notice both answers equal 35,612,815
With that explanation out of the way, let's continue. Next, we take the number 35,612,815 and divide it by 2:
35,612,815 ÷ 2 = 17,806,407.5
If the quotient is a whole number, then 2 and 17,806,407.5 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 | 35,612,815 | |
| -1 | -35,612,815 |
Now, we try dividing 35,612,815 by 3:
35,612,815 ÷ 3 = 11,870,938.3333
If the quotient is a whole number, then 3 and 11,870,938.3333 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 | 35,612,815 | |
| -1 | -35,612,815 |
Let's try dividing by 4:
35,612,815 ÷ 4 = 8,903,203.75
If the quotient is a whole number, then 4 and 8,903,203.75 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 | 35,612,815 | |
| -1 | 35,612,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 23,663 | 118,315 | 165,641 | 828,205 | 1,017,509 | 5,087,545 | 7,122,563 | 35,612,815 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -23,663 | -118,315 | -165,641 | -828,205 | -1,017,509 | -5,087,545 | -7,122,563 | -35,612,815 |
