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 67,531,285, 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 | 67,531,285 | |
| -1 | -67,531,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,531,285.
Example:
1 x 67,531,285 = 67,531,285
and
-1 x -67,531,285 = 67,531,285
Notice both answers equal 67,531,285
With that explanation out of the way, let's continue. Next, we take the number 67,531,285 and divide it by 2:
67,531,285 ÷ 2 = 33,765,642.5
If the quotient is a whole number, then 2 and 33,765,642.5 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 | 67,531,285 | |
| -1 | -67,531,285 |
Now, we try dividing 67,531,285 by 3:
67,531,285 ÷ 3 = 22,510,428.3333
If the quotient is a whole number, then 3 and 22,510,428.3333 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 | 67,531,285 | |
| -1 | -67,531,285 |
Let's try dividing by 4:
67,531,285 ÷ 4 = 16,882,821.25
If the quotient is a whole number, then 4 and 16,882,821.25 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 | 67,531,285 | |
| -1 | 67,531,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 43 | 145 | 215 | 1,247 | 6,235 | 10,831 | 54,155 | 314,099 | 465,733 | 1,570,495 | 2,328,665 | 13,506,257 | 67,531,285 |
| -1 | -5 | -29 | -43 | -145 | -215 | -1,247 | -6,235 | -10,831 | -54,155 | -314,099 | -465,733 | -1,570,495 | -2,328,665 | -13,506,257 | -67,531,285 |
