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 83,013,325, 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 | 83,013,325 | |
| -1 | -83,013,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,013,325.
Example:
1 x 83,013,325 = 83,013,325
and
-1 x -83,013,325 = 83,013,325
Notice both answers equal 83,013,325
With that explanation out of the way, let's continue. Next, we take the number 83,013,325 and divide it by 2:
83,013,325 ÷ 2 = 41,506,662.5
If the quotient is a whole number, then 2 and 41,506,662.5 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 | 83,013,325 | |
| -1 | -83,013,325 |
Now, we try dividing 83,013,325 by 3:
83,013,325 ÷ 3 = 27,671,108.3333
If the quotient is a whole number, then 3 and 27,671,108.3333 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 | 83,013,325 | |
| -1 | -83,013,325 |
Let's try dividing by 4:
83,013,325 ÷ 4 = 20,753,331.25
If the quotient is a whole number, then 4 and 20,753,331.25 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 | 83,013,325 | |
| -1 | 83,013,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 529 | 575 | 2,645 | 6,277 | 13,225 | 31,385 | 144,371 | 156,925 | 721,855 | 3,320,533 | 3,609,275 | 16,602,665 | 83,013,325 |
| -1 | -5 | -23 | -25 | -115 | -529 | -575 | -2,645 | -6,277 | -13,225 | -31,385 | -144,371 | -156,925 | -721,855 | -3,320,533 | -3,609,275 | -16,602,665 | -83,013,325 |
