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 29,487,563, 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 | 29,487,563 | |
| -1 | -29,487,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,487,563.
Example:
1 x 29,487,563 = 29,487,563
and
-1 x -29,487,563 = 29,487,563
Notice both answers equal 29,487,563
With that explanation out of the way, let's continue. Next, we take the number 29,487,563 and divide it by 2:
29,487,563 ÷ 2 = 14,743,781.5
If the quotient is a whole number, then 2 and 14,743,781.5 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 | 29,487,563 | |
| -1 | -29,487,563 |
Now, we try dividing 29,487,563 by 3:
29,487,563 ÷ 3 = 9,829,187.6667
If the quotient is a whole number, then 3 and 9,829,187.6667 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 | 29,487,563 | |
| -1 | -29,487,563 |
Let's try dividing by 4:
29,487,563 ÷ 4 = 7,371,890.75
If the quotient is a whole number, then 4 and 7,371,890.75 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 | 29,487,563 | |
| -1 | 29,487,563 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 133 | 361 | 931 | 1,667 | 2,527 | 11,669 | 17,689 | 31,673 | 81,683 | 221,711 | 601,787 | 1,551,977 | 4,212,509 | 29,487,563 |
| -1 | -7 | -19 | -49 | -133 | -361 | -931 | -1,667 | -2,527 | -11,669 | -17,689 | -31,673 | -81,683 | -221,711 | -601,787 | -1,551,977 | -4,212,509 | -29,487,563 |
