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 142,213,435, 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 | 142,213,435 | |
| -1 | -142,213,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,213,435.
Example:
1 x 142,213,435 = 142,213,435
and
-1 x -142,213,435 = 142,213,435
Notice both answers equal 142,213,435
With that explanation out of the way, let's continue. Next, we take the number 142,213,435 and divide it by 2:
142,213,435 ÷ 2 = 71,106,717.5
If the quotient is a whole number, then 2 and 71,106,717.5 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 | 142,213,435 | |
| -1 | -142,213,435 |
Now, we try dividing 142,213,435 by 3:
142,213,435 ÷ 3 = 47,404,478.3333
If the quotient is a whole number, then 3 and 47,404,478.3333 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 | 142,213,435 | |
| -1 | -142,213,435 |
Let's try dividing by 4:
142,213,435 ÷ 4 = 35,553,358.75
If the quotient is a whole number, then 4 and 35,553,358.75 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 | 142,213,435 | |
| -1 | 142,213,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 49 | 65 | 91 | 245 | 455 | 637 | 3,185 | 44,651 | 223,255 | 312,557 | 580,463 | 1,562,785 | 2,187,899 | 2,902,315 | 4,063,241 | 10,939,495 | 20,316,205 | 28,442,687 | 142,213,435 |
| -1 | -5 | -7 | -13 | -35 | -49 | -65 | -91 | -245 | -455 | -637 | -3,185 | -44,651 | -223,255 | -312,557 | -580,463 | -1,562,785 | -2,187,899 | -2,902,315 | -4,063,241 | -10,939,495 | -20,316,205 | -28,442,687 | -142,213,435 |
