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 145,541,335, 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 | 145,541,335 | |
| -1 | -145,541,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,541,335.
Example:
1 x 145,541,335 = 145,541,335
and
-1 x -145,541,335 = 145,541,335
Notice both answers equal 145,541,335
With that explanation out of the way, let's continue. Next, we take the number 145,541,335 and divide it by 2:
145,541,335 ÷ 2 = 72,770,667.5
If the quotient is a whole number, then 2 and 72,770,667.5 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 | 145,541,335 | |
| -1 | -145,541,335 |
Now, we try dividing 145,541,335 by 3:
145,541,335 ÷ 3 = 48,513,778.3333
If the quotient is a whole number, then 3 and 48,513,778.3333 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 | 145,541,335 | |
| -1 | -145,541,335 |
Let's try dividing by 4:
145,541,335 ÷ 4 = 36,385,333.75
If the quotient is a whole number, then 4 and 36,385,333.75 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 | 145,541,335 | |
| -1 | 145,541,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 167 | 835 | 2,839 | 10,253 | 14,195 | 51,265 | 174,301 | 871,505 | 1,712,251 | 8,561,255 | 29,108,267 | 145,541,335 |
| -1 | -5 | -17 | -85 | -167 | -835 | -2,839 | -10,253 | -14,195 | -51,265 | -174,301 | -871,505 | -1,712,251 | -8,561,255 | -29,108,267 | -145,541,335 |
