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 72,348,067, 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 | 72,348,067 | |
| -1 | -72,348,067 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 72,348,067.
Example:
1 x 72,348,067 = 72,348,067
and
-1 x -72,348,067 = 72,348,067
Notice both answers equal 72,348,067
With that explanation out of the way, let's continue. Next, we take the number 72,348,067 and divide it by 2:
72,348,067 ÷ 2 = 36,174,033.5
If the quotient is a whole number, then 2 and 36,174,033.5 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 | 72,348,067 | |
| -1 | -72,348,067 |
Now, we try dividing 72,348,067 by 3:
72,348,067 ÷ 3 = 24,116,022.3333
If the quotient is a whole number, then 3 and 24,116,022.3333 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 | 72,348,067 | |
| -1 | -72,348,067 |
Let's try dividing by 4:
72,348,067 ÷ 4 = 18,087,016.75
If the quotient is a whole number, then 4 and 18,087,016.75 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 | 72,348,067 | |
| -1 | 72,348,067 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 41 | 209 | 451 | 779 | 8,443 | 8,569 | 92,873 | 160,417 | 346,163 | 1,764,587 | 3,807,793 | 6,577,097 | 72,348,067 |
| -1 | -11 | -19 | -41 | -209 | -451 | -779 | -8,443 | -8,569 | -92,873 | -160,417 | -346,163 | -1,764,587 | -3,807,793 | -6,577,097 | -72,348,067 |
