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 143,125,435, 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 | 143,125,435 | |
| -1 | -143,125,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,125,435.
Example:
1 x 143,125,435 = 143,125,435
and
-1 x -143,125,435 = 143,125,435
Notice both answers equal 143,125,435
With that explanation out of the way, let's continue. Next, we take the number 143,125,435 and divide it by 2:
143,125,435 ÷ 2 = 71,562,717.5
If the quotient is a whole number, then 2 and 71,562,717.5 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 | 143,125,435 | |
| -1 | -143,125,435 |
Now, we try dividing 143,125,435 by 3:
143,125,435 ÷ 3 = 47,708,478.3333
If the quotient is a whole number, then 3 and 47,708,478.3333 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 | 143,125,435 | |
| -1 | -143,125,435 |
Let's try dividing by 4:
143,125,435 ÷ 4 = 35,781,358.75
If the quotient is a whole number, then 4 and 35,781,358.75 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 | 143,125,435 | |
| -1 | 143,125,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 851 | 4,255 | 33,637 | 168,185 | 773,651 | 1,244,569 | 3,868,255 | 6,222,845 | 28,625,087 | 143,125,435 |
| -1 | -5 | -23 | -37 | -115 | -185 | -851 | -4,255 | -33,637 | -168,185 | -773,651 | -1,244,569 | -3,868,255 | -6,222,845 | -28,625,087 | -143,125,435 |
