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 72,822,635, 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 | 72,822,635 | |
| -1 | -72,822,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 72,822,635.
Example:
1 x 72,822,635 = 72,822,635
and
-1 x -72,822,635 = 72,822,635
Notice both answers equal 72,822,635
With that explanation out of the way, let's continue. Next, we take the number 72,822,635 and divide it by 2:
72,822,635 ÷ 2 = 36,411,317.5
If the quotient is a whole number, then 2 and 36,411,317.5 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 | 72,822,635 | |
| -1 | -72,822,635 |
Now, we try dividing 72,822,635 by 3:
72,822,635 ÷ 3 = 24,274,211.6667
If the quotient is a whole number, then 3 and 24,274,211.6667 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 | 72,822,635 | |
| -1 | -72,822,635 |
Let's try dividing by 4:
72,822,635 ÷ 4 = 18,205,658.75
If the quotient is a whole number, then 4 and 18,205,658.75 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 | 72,822,635 | |
| -1 | 72,822,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 181 | 335 | 905 | 1,201 | 6,005 | 12,127 | 60,635 | 80,467 | 217,381 | 402,335 | 1,086,905 | 14,564,527 | 72,822,635 |
| -1 | -5 | -67 | -181 | -335 | -905 | -1,201 | -6,005 | -12,127 | -60,635 | -80,467 | -217,381 | -402,335 | -1,086,905 | -14,564,527 | -72,822,635 |
