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 146,156,569, 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 | 146,156,569 | |
| -1 | -146,156,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,156,569.
Example:
1 x 146,156,569 = 146,156,569
and
-1 x -146,156,569 = 146,156,569
Notice both answers equal 146,156,569
With that explanation out of the way, let's continue. Next, we take the number 146,156,569 and divide it by 2:
146,156,569 ÷ 2 = 73,078,284.5
If the quotient is a whole number, then 2 and 73,078,284.5 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 | 146,156,569 | |
| -1 | -146,156,569 |
Now, we try dividing 146,156,569 by 3:
146,156,569 ÷ 3 = 48,718,856.3333
If the quotient is a whole number, then 3 and 48,718,856.3333 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 | 146,156,569 | |
| -1 | -146,156,569 |
Let's try dividing by 4:
146,156,569 ÷ 4 = 36,539,142.25
If the quotient is a whole number, then 4 and 36,539,142.25 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 | 146,156,569 | |
| -1 | 146,156,569 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 131 | 247 | 1,703 | 2,489 | 4,517 | 32,357 | 58,721 | 85,823 | 591,727 | 1,115,699 | 7,692,451 | 11,242,813 | 146,156,569 |
| -1 | -13 | -19 | -131 | -247 | -1,703 | -2,489 | -4,517 | -32,357 | -58,721 | -85,823 | -591,727 | -1,115,699 | -7,692,451 | -11,242,813 | -146,156,569 |
