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 146,234,621, 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 | 146,234,621 | |
| -1 | -146,234,621 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,234,621.
Example:
1 x 146,234,621 = 146,234,621
and
-1 x -146,234,621 = 146,234,621
Notice both answers equal 146,234,621
With that explanation out of the way, let's continue. Next, we take the number 146,234,621 and divide it by 2:
146,234,621 ÷ 2 = 73,117,310.5
If the quotient is a whole number, then 2 and 73,117,310.5 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 | 146,234,621 | |
| -1 | -146,234,621 |
Now, we try dividing 146,234,621 by 3:
146,234,621 ÷ 3 = 48,744,873.6667
If the quotient is a whole number, then 3 and 48,744,873.6667 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 | 146,234,621 | |
| -1 | -146,234,621 |
Let's try dividing by 4:
146,234,621 ÷ 4 = 36,558,655.25
If the quotient is a whole number, then 4 and 36,558,655.25 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 | 146,234,621 | |
| -1 | 146,234,621 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 23 | 247 | 299 | 437 | 5,681 | 25,741 | 334,633 | 489,079 | 592,043 | 6,358,027 | 7,696,559 | 11,248,817 | 146,234,621 |
| -1 | -13 | -19 | -23 | -247 | -299 | -437 | -5,681 | -25,741 | -334,633 | -489,079 | -592,043 | -6,358,027 | -7,696,559 | -11,248,817 | -146,234,621 |
