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 145,005,325, 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 | 145,005,325 | |
| -1 | -145,005,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,005,325.
Example:
1 x 145,005,325 = 145,005,325
and
-1 x -145,005,325 = 145,005,325
Notice both answers equal 145,005,325
With that explanation out of the way, let's continue. Next, we take the number 145,005,325 and divide it by 2:
145,005,325 ÷ 2 = 72,502,662.5
If the quotient is a whole number, then 2 and 72,502,662.5 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 | 145,005,325 | |
| -1 | -145,005,325 |
Now, we try dividing 145,005,325 by 3:
145,005,325 ÷ 3 = 48,335,108.3333
If the quotient is a whole number, then 3 and 48,335,108.3333 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 | 145,005,325 | |
| -1 | -145,005,325 |
Let's try dividing by 4:
145,005,325 ÷ 4 = 36,251,331.25
If the quotient is a whole number, then 4 and 36,251,331.25 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 | 145,005,325 | |
| -1 | 145,005,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 271 | 425 | 1,259 | 1,355 | 4,607 | 6,295 | 6,775 | 21,403 | 23,035 | 31,475 | 107,015 | 115,175 | 341,189 | 535,075 | 1,705,945 | 5,800,213 | 8,529,725 | 29,001,065 | 145,005,325 |
| -1 | -5 | -17 | -25 | -85 | -271 | -425 | -1,259 | -1,355 | -4,607 | -6,295 | -6,775 | -21,403 | -23,035 | -31,475 | -107,015 | -115,175 | -341,189 | -535,075 | -1,705,945 | -5,800,213 | -8,529,725 | -29,001,065 | -145,005,325 |
