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 146,285,645, 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 | 146,285,645 | |
| -1 | -146,285,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,285,645.
Example:
1 x 146,285,645 = 146,285,645
and
-1 x -146,285,645 = 146,285,645
Notice both answers equal 146,285,645
With that explanation out of the way, let's continue. Next, we take the number 146,285,645 and divide it by 2:
146,285,645 ÷ 2 = 73,142,822.5
If the quotient is a whole number, then 2 and 73,142,822.5 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 | 146,285,645 | |
| -1 | -146,285,645 |
Now, we try dividing 146,285,645 by 3:
146,285,645 ÷ 3 = 48,761,881.6667
If the quotient is a whole number, then 3 and 48,761,881.6667 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 | 146,285,645 | |
| -1 | -146,285,645 |
Let's try dividing by 4:
146,285,645 ÷ 4 = 36,571,411.25
If the quotient is a whole number, then 4 and 36,571,411.25 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 | 146,285,645 | |
| -1 | 146,285,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 881 | 3,019 | 4,405 | 9,691 | 15,095 | 33,209 | 48,455 | 166,045 | 2,659,739 | 13,298,695 | 29,257,129 | 146,285,645 |
| -1 | -5 | -11 | -55 | -881 | -3,019 | -4,405 | -9,691 | -15,095 | -33,209 | -48,455 | -166,045 | -2,659,739 | -13,298,695 | -29,257,129 | -146,285,645 |
