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 87,625,735, 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 | 87,625,735 | |
| -1 | -87,625,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 87,625,735.
Example:
1 x 87,625,735 = 87,625,735
and
-1 x -87,625,735 = 87,625,735
Notice both answers equal 87,625,735
With that explanation out of the way, let's continue. Next, we take the number 87,625,735 and divide it by 2:
87,625,735 ÷ 2 = 43,812,867.5
If the quotient is a whole number, then 2 and 43,812,867.5 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 | 87,625,735 | |
| -1 | -87,625,735 |
Now, we try dividing 87,625,735 by 3:
87,625,735 ÷ 3 = 29,208,578.3333
If the quotient is a whole number, then 3 and 29,208,578.3333 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 | 87,625,735 | |
| -1 | -87,625,735 |
Let's try dividing by 4:
87,625,735 ÷ 4 = 21,906,433.75
If the quotient is a whole number, then 4 and 21,906,433.75 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 | 87,625,735 | |
| -1 | 87,625,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 167 | 835 | 2,839 | 6,173 | 14,195 | 30,865 | 104,941 | 524,705 | 1,030,891 | 5,154,455 | 17,525,147 | 87,625,735 |
| -1 | -5 | -17 | -85 | -167 | -835 | -2,839 | -6,173 | -14,195 | -30,865 | -104,941 | -524,705 | -1,030,891 | -5,154,455 | -17,525,147 | -87,625,735 |
