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 730,012,547, 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 | 730,012,547 | |
| -1 | -730,012,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 730,012,547.
Example:
1 x 730,012,547 = 730,012,547
and
-1 x -730,012,547 = 730,012,547
Notice both answers equal 730,012,547
With that explanation out of the way, let's continue. Next, we take the number 730,012,547 and divide it by 2:
730,012,547 ÷ 2 = 365,006,273.5
If the quotient is a whole number, then 2 and 365,006,273.5 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 | 730,012,547 | |
| -1 | -730,012,547 |
Now, we try dividing 730,012,547 by 3:
730,012,547 ÷ 3 = 243,337,515.6667
If the quotient is a whole number, then 3 and 243,337,515.6667 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 | 730,012,547 | |
| -1 | -730,012,547 |
Let's try dividing by 4:
730,012,547 ÷ 4 = 182,503,136.75
If the quotient is a whole number, then 4 and 182,503,136.75 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 | 730,012,547 | |
| -1 | 730,012,547 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 101 | 209 | 1,111 | 1,919 | 21,109 | 34,583 | 380,413 | 657,077 | 3,492,883 | 7,227,847 | 38,421,713 | 66,364,777 | 730,012,547 |
| -1 | -11 | -19 | -101 | -209 | -1,111 | -1,919 | -21,109 | -34,583 | -380,413 | -657,077 | -3,492,883 | -7,227,847 | -38,421,713 | -66,364,777 | -730,012,547 |
