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 145,105,435, 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 | 145,105,435 | |
| -1 | -145,105,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,105,435.
Example:
1 x 145,105,435 = 145,105,435
and
-1 x -145,105,435 = 145,105,435
Notice both answers equal 145,105,435
With that explanation out of the way, let's continue. Next, we take the number 145,105,435 and divide it by 2:
145,105,435 ÷ 2 = 72,552,717.5
If the quotient is a whole number, then 2 and 72,552,717.5 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 | 145,105,435 | |
| -1 | -145,105,435 |
Now, we try dividing 145,105,435 by 3:
145,105,435 ÷ 3 = 48,368,478.3333
If the quotient is a whole number, then 3 and 48,368,478.3333 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 | 145,105,435 | |
| -1 | -145,105,435 |
Let's try dividing by 4:
145,105,435 ÷ 4 = 36,276,358.75
If the quotient is a whole number, then 4 and 36,276,358.75 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 | 145,105,435 | |
| -1 | 145,105,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 331 | 1,655 | 2,039 | 10,195 | 14,233 | 71,165 | 87,677 | 438,385 | 674,909 | 3,374,545 | 29,021,087 | 145,105,435 |
| -1 | -5 | -43 | -215 | -331 | -1,655 | -2,039 | -10,195 | -14,233 | -71,165 | -87,677 | -438,385 | -674,909 | -3,374,545 | -29,021,087 | -145,105,435 |
