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 87,609,265, 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 | 87,609,265 | |
| -1 | -87,609,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 87,609,265.
Example:
1 x 87,609,265 = 87,609,265
and
-1 x -87,609,265 = 87,609,265
Notice both answers equal 87,609,265
With that explanation out of the way, let's continue. Next, we take the number 87,609,265 and divide it by 2:
87,609,265 ÷ 2 = 43,804,632.5
If the quotient is a whole number, then 2 and 43,804,632.5 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 | 87,609,265 | |
| -1 | -87,609,265 |
Now, we try dividing 87,609,265 by 3:
87,609,265 ÷ 3 = 29,203,088.3333
If the quotient is a whole number, then 3 and 29,203,088.3333 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 | 87,609,265 | |
| -1 | -87,609,265 |
Let's try dividing by 4:
87,609,265 ÷ 4 = 21,902,316.25
If the quotient is a whole number, then 4 and 21,902,316.25 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 | 87,609,265 | |
| -1 | 87,609,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 265 | 269 | 1,229 | 1,345 | 6,145 | 14,257 | 65,137 | 71,285 | 325,685 | 330,601 | 1,653,005 | 17,521,853 | 87,609,265 |
| -1 | -5 | -53 | -265 | -269 | -1,229 | -1,345 | -6,145 | -14,257 | -65,137 | -71,285 | -325,685 | -330,601 | -1,653,005 | -17,521,853 | -87,609,265 |
