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 724,042,267, 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 | 724,042,267 | |
| -1 | -724,042,267 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 724,042,267.
Example:
1 x 724,042,267 = 724,042,267
and
-1 x -724,042,267 = 724,042,267
Notice both answers equal 724,042,267
With that explanation out of the way, let's continue. Next, we take the number 724,042,267 and divide it by 2:
724,042,267 ÷ 2 = 362,021,133.5
If the quotient is a whole number, then 2 and 362,021,133.5 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 | 724,042,267 | |
| -1 | -724,042,267 |
Now, we try dividing 724,042,267 by 3:
724,042,267 ÷ 3 = 241,347,422.3333
If the quotient is a whole number, then 3 and 241,347,422.3333 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 | 724,042,267 | |
| -1 | -724,042,267 |
Let's try dividing by 4:
724,042,267 ÷ 4 = 181,010,566.75
If the quotient is a whole number, then 4 and 181,010,566.75 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 | 724,042,267 | |
| -1 | 724,042,267 |
If you did it right, you will end up with this table:
| 1 | 13 | 67 | 277 | 871 | 3,001 | 3,601 | 18,559 | 39,013 | 201,067 | 241,267 | 831,277 | 2,613,871 | 10,806,601 | 55,695,559 | 724,042,267 |
| -1 | -13 | -67 | -277 | -871 | -3,001 | -3,601 | -18,559 | -39,013 | -201,067 | -241,267 | -831,277 | -2,613,871 | -10,806,601 | -55,695,559 | -724,042,267 |
