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 146,202,703, 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 | 146,202,703 | |
| -1 | -146,202,703 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,202,703.
Example:
1 x 146,202,703 = 146,202,703
and
-1 x -146,202,703 = 146,202,703
Notice both answers equal 146,202,703
With that explanation out of the way, let's continue. Next, we take the number 146,202,703 and divide it by 2:
146,202,703 ÷ 2 = 73,101,351.5
If the quotient is a whole number, then 2 and 73,101,351.5 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 | 146,202,703 | |
| -1 | -146,202,703 |
Now, we try dividing 146,202,703 by 3:
146,202,703 ÷ 3 = 48,734,234.3333
If the quotient is a whole number, then 3 and 48,734,234.3333 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 | 146,202,703 | |
| -1 | -146,202,703 |
Let's try dividing by 4:
146,202,703 ÷ 4 = 36,550,675.75
If the quotient is a whole number, then 4 and 36,550,675.75 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 | 146,202,703 | |
| -1 | 146,202,703 |
If you did it right, you will end up with this table:
| 1 | 17 | 71 | 89 | 1,207 | 1,361 | 1,513 | 6,319 | 23,137 | 96,631 | 107,423 | 121,129 | 1,642,727 | 2,059,193 | 8,600,159 | 146,202,703 |
| -1 | -17 | -71 | -89 | -1,207 | -1,361 | -1,513 | -6,319 | -23,137 | -96,631 | -107,423 | -121,129 | -1,642,727 | -2,059,193 | -8,600,159 | -146,202,703 |
