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 143,425,435, 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 | 143,425,435 | |
| -1 | -143,425,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,425,435.
Example:
1 x 143,425,435 = 143,425,435
and
-1 x -143,425,435 = 143,425,435
Notice both answers equal 143,425,435
With that explanation out of the way, let's continue. Next, we take the number 143,425,435 and divide it by 2:
143,425,435 ÷ 2 = 71,712,717.5
If the quotient is a whole number, then 2 and 71,712,717.5 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 | 143,425,435 | |
| -1 | -143,425,435 |
Now, we try dividing 143,425,435 by 3:
143,425,435 ÷ 3 = 47,808,478.3333
If the quotient is a whole number, then 3 and 47,808,478.3333 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 | 143,425,435 | |
| -1 | -143,425,435 |
Let's try dividing by 4:
143,425,435 ÷ 4 = 35,856,358.75
If the quotient is a whole number, then 4 and 35,856,358.75 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 | 143,425,435 | |
| -1 | 143,425,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 367 | 1,663 | 1,835 | 8,315 | 17,249 | 78,161 | 86,245 | 390,805 | 610,321 | 3,051,605 | 28,685,087 | 143,425,435 |
| -1 | -5 | -47 | -235 | -367 | -1,663 | -1,835 | -8,315 | -17,249 | -78,161 | -86,245 | -390,805 | -610,321 | -3,051,605 | -28,685,087 | -143,425,435 |
