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 72,669,623, 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 | 72,669,623 | |
| -1 | -72,669,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 72,669,623.
Example:
1 x 72,669,623 = 72,669,623
and
-1 x -72,669,623 = 72,669,623
Notice both answers equal 72,669,623
With that explanation out of the way, let's continue. Next, we take the number 72,669,623 and divide it by 2:
72,669,623 ÷ 2 = 36,334,811.5
If the quotient is a whole number, then 2 and 36,334,811.5 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 | 72,669,623 | |
| -1 | -72,669,623 |
Now, we try dividing 72,669,623 by 3:
72,669,623 ÷ 3 = 24,223,207.6667
If the quotient is a whole number, then 3 and 24,223,207.6667 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 | 72,669,623 | |
| -1 | -72,669,623 |
Let's try dividing by 4:
72,669,623 ÷ 4 = 18,167,405.75
If the quotient is a whole number, then 4 and 18,167,405.75 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 | 72,669,623 | |
| -1 | 72,669,623 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 239 | 247 | 1,231 | 3,107 | 4,541 | 16,003 | 23,389 | 59,033 | 294,209 | 304,057 | 3,824,717 | 5,589,971 | 72,669,623 |
| -1 | -13 | -19 | -239 | -247 | -1,231 | -3,107 | -4,541 | -16,003 | -23,389 | -59,033 | -294,209 | -304,057 | -3,824,717 | -5,589,971 | -72,669,623 |
