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 92,791,489, 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 | 92,791,489 | |
| -1 | -92,791,489 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 92,791,489.
Example:
1 x 92,791,489 = 92,791,489
and
-1 x -92,791,489 = 92,791,489
Notice both answers equal 92,791,489
With that explanation out of the way, let's continue. Next, we take the number 92,791,489 and divide it by 2:
92,791,489 ÷ 2 = 46,395,744.5
If the quotient is a whole number, then 2 and 46,395,744.5 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 | 92,791,489 | |
| -1 | -92,791,489 |
Now, we try dividing 92,791,489 by 3:
92,791,489 ÷ 3 = 30,930,496.3333
If the quotient is a whole number, then 3 and 30,930,496.3333 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 | 92,791,489 | |
| -1 | -92,791,489 |
Let's try dividing by 4:
92,791,489 ÷ 4 = 23,197,872.25
If the quotient is a whole number, then 4 and 23,197,872.25 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 | 92,791,489 | |
| -1 | 92,791,489 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 89 | 329 | 623 | 3,169 | 4,183 | 22,183 | 29,281 | 148,943 | 282,041 | 1,042,601 | 1,974,287 | 13,255,927 | 92,791,489 |
| -1 | -7 | -47 | -89 | -329 | -623 | -3,169 | -4,183 | -22,183 | -29,281 | -148,943 | -282,041 | -1,042,601 | -1,974,287 | -13,255,927 | -92,791,489 |
