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 153,343,001, 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 | 153,343,001 | |
| -1 | -153,343,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,343,001.
Example:
1 x 153,343,001 = 153,343,001
and
-1 x -153,343,001 = 153,343,001
Notice both answers equal 153,343,001
With that explanation out of the way, let's continue. Next, we take the number 153,343,001 and divide it by 2:
153,343,001 ÷ 2 = 76,671,500.5
If the quotient is a whole number, then 2 and 76,671,500.5 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 | 153,343,001 | |
| -1 | -153,343,001 |
Now, we try dividing 153,343,001 by 3:
153,343,001 ÷ 3 = 51,114,333.6667
If the quotient is a whole number, then 3 and 51,114,333.6667 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 | 153,343,001 | |
| -1 | -153,343,001 |
Let's try dividing by 4:
153,343,001 ÷ 4 = 38,335,750.25
If the quotient is a whole number, then 4 and 38,335,750.25 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 | 153,343,001 | |
| -1 | 153,343,001 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 103 | 161 | 721 | 1,127 | 1,321 | 2,369 | 5,047 | 9,247 | 16,583 | 30,383 | 64,729 | 116,081 | 136,063 | 212,681 | 952,441 | 1,488,767 | 3,129,449 | 6,667,087 | 21,906,143 | 153,343,001 |
| -1 | -7 | -23 | -49 | -103 | -161 | -721 | -1,127 | -1,321 | -2,369 | -5,047 | -9,247 | -16,583 | -30,383 | -64,729 | -116,081 | -136,063 | -212,681 | -952,441 | -1,488,767 | -3,129,449 | -6,667,087 | -21,906,143 | -153,343,001 |
