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 144,137,569, 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 | 144,137,569 | |
| -1 | -144,137,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,137,569.
Example:
1 x 144,137,569 = 144,137,569
and
-1 x -144,137,569 = 144,137,569
Notice both answers equal 144,137,569
With that explanation out of the way, let's continue. Next, we take the number 144,137,569 and divide it by 2:
144,137,569 ÷ 2 = 72,068,784.5
If the quotient is a whole number, then 2 and 72,068,784.5 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 | 144,137,569 | |
| -1 | -144,137,569 |
Now, we try dividing 144,137,569 by 3:
144,137,569 ÷ 3 = 48,045,856.3333
If the quotient is a whole number, then 3 and 48,045,856.3333 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 | 144,137,569 | |
| -1 | -144,137,569 |
Let's try dividing by 4:
144,137,569 ÷ 4 = 36,034,392.25
If the quotient is a whole number, then 4 and 36,034,392.25 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 | 144,137,569 | |
| -1 | 144,137,569 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 67 | 899 | 1,943 | 2,077 | 2,393 | 60,233 | 69,397 | 74,183 | 160,331 | 2,151,307 | 4,649,599 | 4,970,261 | 144,137,569 |
| -1 | -29 | -31 | -67 | -899 | -1,943 | -2,077 | -2,393 | -60,233 | -69,397 | -74,183 | -160,331 | -2,151,307 | -4,649,599 | -4,970,261 | -144,137,569 |
