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 130,411,225, 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 | 130,411,225 | |
| -1 | -130,411,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,411,225.
Example:
1 x 130,411,225 = 130,411,225
and
-1 x -130,411,225 = 130,411,225
Notice both answers equal 130,411,225
With that explanation out of the way, let's continue. Next, we take the number 130,411,225 and divide it by 2:
130,411,225 ÷ 2 = 65,205,612.5
If the quotient is a whole number, then 2 and 65,205,612.5 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 | 130,411,225 | |
| -1 | -130,411,225 |
Now, we try dividing 130,411,225 by 3:
130,411,225 ÷ 3 = 43,470,408.3333
If the quotient is a whole number, then 3 and 43,470,408.3333 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 | 130,411,225 | |
| -1 | -130,411,225 |
Let's try dividing by 4:
130,411,225 ÷ 4 = 32,602,806.25
If the quotient is a whole number, then 4 and 32,602,806.25 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 | 130,411,225 | |
| -1 | 130,411,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 79 | 175 | 395 | 553 | 1,975 | 2,765 | 9,433 | 13,825 | 47,165 | 66,031 | 235,825 | 330,155 | 745,207 | 1,650,775 | 3,726,035 | 5,216,449 | 18,630,175 | 26,082,245 | 130,411,225 |
| -1 | -5 | -7 | -25 | -35 | -79 | -175 | -395 | -553 | -1,975 | -2,765 | -9,433 | -13,825 | -47,165 | -66,031 | -235,825 | -330,155 | -745,207 | -1,650,775 | -3,726,035 | -5,216,449 | -18,630,175 | -26,082,245 | -130,411,225 |
