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 142,213,337, 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 | 142,213,337 | |
| -1 | -142,213,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,213,337.
Example:
1 x 142,213,337 = 142,213,337
and
-1 x -142,213,337 = 142,213,337
Notice both answers equal 142,213,337
With that explanation out of the way, let's continue. Next, we take the number 142,213,337 and divide it by 2:
142,213,337 ÷ 2 = 71,106,668.5
If the quotient is a whole number, then 2 and 71,106,668.5 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 | 142,213,337 | |
| -1 | -142,213,337 |
Now, we try dividing 142,213,337 by 3:
142,213,337 ÷ 3 = 47,404,445.6667
If the quotient is a whole number, then 3 and 47,404,445.6667 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 | 142,213,337 | |
| -1 | -142,213,337 |
Let's try dividing by 4:
142,213,337 ÷ 4 = 35,553,334.25
If the quotient is a whole number, then 4 and 35,553,334.25 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 | 142,213,337 | |
| -1 | 142,213,337 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 217 | 251 | 373 | 1,519 | 1,757 | 2,611 | 7,781 | 11,563 | 12,299 | 18,277 | 54,467 | 80,941 | 93,623 | 381,269 | 566,587 | 655,361 | 2,902,313 | 4,587,527 | 20,316,191 | 142,213,337 |
| -1 | -7 | -31 | -49 | -217 | -251 | -373 | -1,519 | -1,757 | -2,611 | -7,781 | -11,563 | -12,299 | -18,277 | -54,467 | -80,941 | -93,623 | -381,269 | -566,587 | -655,361 | -2,902,313 | -4,587,527 | -20,316,191 | -142,213,337 |
