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 145,070,623, 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 | 145,070,623 | |
| -1 | -145,070,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,070,623.
Example:
1 x 145,070,623 = 145,070,623
and
-1 x -145,070,623 = 145,070,623
Notice both answers equal 145,070,623
With that explanation out of the way, let's continue. Next, we take the number 145,070,623 and divide it by 2:
145,070,623 ÷ 2 = 72,535,311.5
If the quotient is a whole number, then 2 and 72,535,311.5 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 | 145,070,623 | |
| -1 | -145,070,623 |
Now, we try dividing 145,070,623 by 3:
145,070,623 ÷ 3 = 48,356,874.3333
If the quotient is a whole number, then 3 and 48,356,874.3333 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 | 145,070,623 | |
| -1 | -145,070,623 |
Let's try dividing by 4:
145,070,623 ÷ 4 = 36,267,655.75
If the quotient is a whole number, then 4 and 36,267,655.75 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 | 145,070,623 | |
| -1 | 145,070,623 |
If you did it right, you will end up with this table:
| 1 | 47 | 79 | 89 | 439 | 3,713 | 4,183 | 7,031 | 20,633 | 34,681 | 39,071 | 330,457 | 1,630,007 | 1,836,337 | 3,086,609 | 145,070,623 |
| -1 | -47 | -79 | -89 | -439 | -3,713 | -4,183 | -7,031 | -20,633 | -34,681 | -39,071 | -330,457 | -1,630,007 | -1,836,337 | -3,086,609 | -145,070,623 |
