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 142,323,467, 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 | 142,323,467 | |
| -1 | -142,323,467 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,323,467.
Example:
1 x 142,323,467 = 142,323,467
and
-1 x -142,323,467 = 142,323,467
Notice both answers equal 142,323,467
With that explanation out of the way, let's continue. Next, we take the number 142,323,467 and divide it by 2:
142,323,467 ÷ 2 = 71,161,733.5
If the quotient is a whole number, then 2 and 71,161,733.5 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 | 142,323,467 | |
| -1 | -142,323,467 |
Now, we try dividing 142,323,467 by 3:
142,323,467 ÷ 3 = 47,441,155.6667
If the quotient is a whole number, then 3 and 47,441,155.6667 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 | 142,323,467 | |
| -1 | -142,323,467 |
Let's try dividing by 4:
142,323,467 ÷ 4 = 35,580,866.75
If the quotient is a whole number, then 4 and 35,580,866.75 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 | 142,323,467 | |
| -1 | 142,323,467 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 121 | 143 | 173 | 523 | 1,573 | 1,903 | 2,249 | 5,753 | 6,799 | 20,933 | 24,739 | 63,283 | 74,789 | 90,479 | 272,129 | 822,679 | 995,269 | 1,176,227 | 10,947,959 | 12,938,497 | 142,323,467 |
| -1 | -11 | -13 | -121 | -143 | -173 | -523 | -1,573 | -1,903 | -2,249 | -5,753 | -6,799 | -20,933 | -24,739 | -63,283 | -74,789 | -90,479 | -272,129 | -822,679 | -995,269 | -1,176,227 | -10,947,959 | -12,938,497 | -142,323,467 |
