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 143,725,705, 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 | 143,725,705 | |
| -1 | -143,725,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,725,705.
Example:
1 x 143,725,705 = 143,725,705
and
-1 x -143,725,705 = 143,725,705
Notice both answers equal 143,725,705
With that explanation out of the way, let's continue. Next, we take the number 143,725,705 and divide it by 2:
143,725,705 ÷ 2 = 71,862,852.5
If the quotient is a whole number, then 2 and 71,862,852.5 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 | 143,725,705 | |
| -1 | -143,725,705 |
Now, we try dividing 143,725,705 by 3:
143,725,705 ÷ 3 = 47,908,568.3333
If the quotient is a whole number, then 3 and 47,908,568.3333 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 | 143,725,705 | |
| -1 | -143,725,705 |
Let's try dividing by 4:
143,725,705 ÷ 4 = 35,931,426.25
If the quotient is a whole number, then 4 and 35,931,426.25 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 | 143,725,705 | |
| -1 | 143,725,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 83 | 205 | 415 | 3,403 | 8,447 | 17,015 | 42,235 | 346,327 | 701,101 | 1,731,635 | 3,505,505 | 28,745,141 | 143,725,705 |
| -1 | -5 | -41 | -83 | -205 | -415 | -3,403 | -8,447 | -17,015 | -42,235 | -346,327 | -701,101 | -1,731,635 | -3,505,505 | -28,745,141 | -143,725,705 |
