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 146,436,661, 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 | 146,436,661 | |
| -1 | -146,436,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,436,661.
Example:
1 x 146,436,661 = 146,436,661
and
-1 x -146,436,661 = 146,436,661
Notice both answers equal 146,436,661
With that explanation out of the way, let's continue. Next, we take the number 146,436,661 and divide it by 2:
146,436,661 ÷ 2 = 73,218,330.5
If the quotient is a whole number, then 2 and 73,218,330.5 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 | 146,436,661 | |
| -1 | -146,436,661 |
Now, we try dividing 146,436,661 by 3:
146,436,661 ÷ 3 = 48,812,220.3333
If the quotient is a whole number, then 3 and 48,812,220.3333 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 | 146,436,661 | |
| -1 | -146,436,661 |
Let's try dividing by 4:
146,436,661 ÷ 4 = 36,609,165.25
If the quotient is a whole number, then 4 and 36,609,165.25 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 | 146,436,661 | |
| -1 | 146,436,661 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 241 | 427 | 1,423 | 1,687 | 9,961 | 14,701 | 86,803 | 102,907 | 342,943 | 607,621 | 2,400,601 | 20,919,523 | 146,436,661 |
| -1 | -7 | -61 | -241 | -427 | -1,423 | -1,687 | -9,961 | -14,701 | -86,803 | -102,907 | -342,943 | -607,621 | -2,400,601 | -20,919,523 | -146,436,661 |
