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 83,823,355, 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 | 83,823,355 | |
| -1 | -83,823,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,823,355.
Example:
1 x 83,823,355 = 83,823,355
and
-1 x -83,823,355 = 83,823,355
Notice both answers equal 83,823,355
With that explanation out of the way, let's continue. Next, we take the number 83,823,355 and divide it by 2:
83,823,355 ÷ 2 = 41,911,677.5
If the quotient is a whole number, then 2 and 41,911,677.5 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 | 83,823,355 | |
| -1 | -83,823,355 |
Now, we try dividing 83,823,355 by 3:
83,823,355 ÷ 3 = 27,941,118.3333
If the quotient is a whole number, then 3 and 27,941,118.3333 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 | 83,823,355 | |
| -1 | -83,823,355 |
Let's try dividing by 4:
83,823,355 ÷ 4 = 20,955,838.75
If the quotient is a whole number, then 4 and 20,955,838.75 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 | 83,823,355 | |
| -1 | 83,823,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 121 | 385 | 605 | 847 | 4,235 | 19,793 | 98,965 | 138,551 | 217,723 | 692,755 | 1,088,615 | 1,524,061 | 2,394,953 | 7,620,305 | 11,974,765 | 16,764,671 | 83,823,355 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -121 | -385 | -605 | -847 | -4,235 | -19,793 | -98,965 | -138,551 | -217,723 | -692,755 | -1,088,615 | -1,524,061 | -2,394,953 | -7,620,305 | -11,974,765 | -16,764,671 | -83,823,355 |
