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 29,487,565, 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 | 29,487,565 | |
| -1 | -29,487,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,487,565.
Example:
1 x 29,487,565 = 29,487,565
and
-1 x -29,487,565 = 29,487,565
Notice both answers equal 29,487,565
With that explanation out of the way, let's continue. Next, we take the number 29,487,565 and divide it by 2:
29,487,565 ÷ 2 = 14,743,782.5
If the quotient is a whole number, then 2 and 14,743,782.5 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 | 29,487,565 | |
| -1 | -29,487,565 |
Now, we try dividing 29,487,565 by 3:
29,487,565 ÷ 3 = 9,829,188.3333
If the quotient is a whole number, then 3 and 9,829,188.3333 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 | 29,487,565 | |
| -1 | -29,487,565 |
Let's try dividing by 4:
29,487,565 ÷ 4 = 7,371,891.25
If the quotient is a whole number, then 4 and 7,371,891.25 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 | 29,487,565 | |
| -1 | 29,487,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 179 | 235 | 701 | 895 | 3,505 | 8,413 | 32,947 | 42,065 | 125,479 | 164,735 | 627,395 | 5,897,513 | 29,487,565 |
| -1 | -5 | -47 | -179 | -235 | -701 | -895 | -3,505 | -8,413 | -32,947 | -42,065 | -125,479 | -164,735 | -627,395 | -5,897,513 | -29,487,565 |
