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 24,478,175, 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 | 24,478,175 | |
| -1 | -24,478,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,478,175.
Example:
1 x 24,478,175 = 24,478,175
and
-1 x -24,478,175 = 24,478,175
Notice both answers equal 24,478,175
With that explanation out of the way, let's continue. Next, we take the number 24,478,175 and divide it by 2:
24,478,175 ÷ 2 = 12,239,087.5
If the quotient is a whole number, then 2 and 12,239,087.5 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 | 24,478,175 | |
| -1 | -24,478,175 |
Now, we try dividing 24,478,175 by 3:
24,478,175 ÷ 3 = 8,159,391.6667
If the quotient is a whole number, then 3 and 8,159,391.6667 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 | 24,478,175 | |
| -1 | -24,478,175 |
Let's try dividing by 4:
24,478,175 ÷ 4 = 6,119,543.75
If the quotient is a whole number, then 4 and 6,119,543.75 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 | 24,478,175 | |
| -1 | 24,478,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 29 | 95 | 145 | 475 | 551 | 725 | 1,777 | 2,755 | 8,885 | 13,775 | 33,763 | 44,425 | 51,533 | 168,815 | 257,665 | 844,075 | 979,127 | 1,288,325 | 4,895,635 | 24,478,175 |
| -1 | -5 | -19 | -25 | -29 | -95 | -145 | -475 | -551 | -725 | -1,777 | -2,755 | -8,885 | -13,775 | -33,763 | -44,425 | -51,533 | -168,815 | -257,665 | -844,075 | -979,127 | -1,288,325 | -4,895,635 | -24,478,175 |
