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 24,670,525, 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 | 24,670,525 | |
| -1 | -24,670,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,670,525.
Example:
1 x 24,670,525 = 24,670,525
and
-1 x -24,670,525 = 24,670,525
Notice both answers equal 24,670,525
With that explanation out of the way, let's continue. Next, we take the number 24,670,525 and divide it by 2:
24,670,525 ÷ 2 = 12,335,262.5
If the quotient is a whole number, then 2 and 12,335,262.5 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 | 24,670,525 | |
| -1 | -24,670,525 |
Now, we try dividing 24,670,525 by 3:
24,670,525 ÷ 3 = 8,223,508.3333
If the quotient is a whole number, then 3 and 8,223,508.3333 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 | 24,670,525 | |
| -1 | -24,670,525 |
Let's try dividing by 4:
24,670,525 ÷ 4 = 6,167,631.25
If the quotient is a whole number, then 4 and 6,167,631.25 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 | 24,670,525 | |
| -1 | 24,670,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 275 | 283 | 317 | 1,415 | 1,585 | 3,113 | 3,487 | 7,075 | 7,925 | 15,565 | 17,435 | 77,825 | 87,175 | 89,711 | 448,555 | 986,821 | 2,242,775 | 4,934,105 | 24,670,525 |
| -1 | -5 | -11 | -25 | -55 | -275 | -283 | -317 | -1,415 | -1,585 | -3,113 | -3,487 | -7,075 | -7,925 | -15,565 | -17,435 | -77,825 | -87,175 | -89,711 | -448,555 | -986,821 | -2,242,775 | -4,934,105 | -24,670,525 |
