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 130,232,245, 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 | 130,232,245 | |
| -1 | -130,232,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,232,245.
Example:
1 x 130,232,245 = 130,232,245
and
-1 x -130,232,245 = 130,232,245
Notice both answers equal 130,232,245
With that explanation out of the way, let's continue. Next, we take the number 130,232,245 and divide it by 2:
130,232,245 ÷ 2 = 65,116,122.5
If the quotient is a whole number, then 2 and 65,116,122.5 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 | 130,232,245 | |
| -1 | -130,232,245 |
Now, we try dividing 130,232,245 by 3:
130,232,245 ÷ 3 = 43,410,748.3333
If the quotient is a whole number, then 3 and 43,410,748.3333 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 | 130,232,245 | |
| -1 | -130,232,245 |
Let's try dividing by 4:
130,232,245 ÷ 4 = 32,558,061.25
If the quotient is a whole number, then 4 and 32,558,061.25 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 | 130,232,245 | |
| -1 | 130,232,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 169 | 715 | 845 | 1,859 | 9,295 | 14,011 | 70,055 | 154,121 | 182,143 | 770,605 | 910,715 | 2,003,573 | 2,367,859 | 10,017,865 | 11,839,295 | 26,046,449 | 130,232,245 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -169 | -715 | -845 | -1,859 | -9,295 | -14,011 | -70,055 | -154,121 | -182,143 | -770,605 | -910,715 | -2,003,573 | -2,367,859 | -10,017,865 | -11,839,295 | -26,046,449 | -130,232,245 |
