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 146,430,265, 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 | 146,430,265 | |
| -1 | -146,430,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,430,265.
Example:
1 x 146,430,265 = 146,430,265
and
-1 x -146,430,265 = 146,430,265
Notice both answers equal 146,430,265
With that explanation out of the way, let's continue. Next, we take the number 146,430,265 and divide it by 2:
146,430,265 ÷ 2 = 73,215,132.5
If the quotient is a whole number, then 2 and 73,215,132.5 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 | 146,430,265 | |
| -1 | -146,430,265 |
Now, we try dividing 146,430,265 by 3:
146,430,265 ÷ 3 = 48,810,088.3333
If the quotient is a whole number, then 3 and 48,810,088.3333 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 | 146,430,265 | |
| -1 | -146,430,265 |
Let's try dividing by 4:
146,430,265 ÷ 4 = 36,607,566.25
If the quotient is a whole number, then 4 and 36,607,566.25 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 | 146,430,265 | |
| -1 | 146,430,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 731 | 3,655 | 40,063 | 200,315 | 681,071 | 1,722,709 | 3,405,355 | 8,613,545 | 29,286,053 | 146,430,265 |
| -1 | -5 | -17 | -43 | -85 | -215 | -731 | -3,655 | -40,063 | -200,315 | -681,071 | -1,722,709 | -3,405,355 | -8,613,545 | -29,286,053 | -146,430,265 |
