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 144,472,207, 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 | 144,472,207 | |
| -1 | -144,472,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,472,207.
Example:
1 x 144,472,207 = 144,472,207
and
-1 x -144,472,207 = 144,472,207
Notice both answers equal 144,472,207
With that explanation out of the way, let's continue. Next, we take the number 144,472,207 and divide it by 2:
144,472,207 ÷ 2 = 72,236,103.5
If the quotient is a whole number, then 2 and 72,236,103.5 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 | 144,472,207 | |
| -1 | -144,472,207 |
Now, we try dividing 144,472,207 by 3:
144,472,207 ÷ 3 = 48,157,402.3333
If the quotient is a whole number, then 3 and 48,157,402.3333 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 | 144,472,207 | |
| -1 | -144,472,207 |
Let's try dividing by 4:
144,472,207 ÷ 4 = 36,118,051.75
If the quotient is a whole number, then 4 and 36,118,051.75 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 | 144,472,207 | |
| -1 | 144,472,207 |
If you did it right, you will end up with this table:
| 1 | 11 | 83 | 229 | 691 | 913 | 2,519 | 7,601 | 19,007 | 57,353 | 158,239 | 209,077 | 630,883 | 1,740,629 | 13,133,837 | 144,472,207 |
| -1 | -11 | -83 | -229 | -691 | -913 | -2,519 | -7,601 | -19,007 | -57,353 | -158,239 | -209,077 | -630,883 | -1,740,629 | -13,133,837 | -144,472,207 |
