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 67,492,255, 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 | 67,492,255 | |
| -1 | -67,492,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,492,255.
Example:
1 x 67,492,255 = 67,492,255
and
-1 x -67,492,255 = 67,492,255
Notice both answers equal 67,492,255
With that explanation out of the way, let's continue. Next, we take the number 67,492,255 and divide it by 2:
67,492,255 ÷ 2 = 33,746,127.5
If the quotient is a whole number, then 2 and 33,746,127.5 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 | 67,492,255 | |
| -1 | -67,492,255 |
Now, we try dividing 67,492,255 by 3:
67,492,255 ÷ 3 = 22,497,418.3333
If the quotient is a whole number, then 3 and 22,497,418.3333 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 | 67,492,255 | |
| -1 | -67,492,255 |
Let's try dividing by 4:
67,492,255 ÷ 4 = 16,873,063.75
If the quotient is a whole number, then 4 and 16,873,063.75 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 | 67,492,255 | |
| -1 | 67,492,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 109 | 185 | 545 | 3,347 | 4,033 | 16,735 | 20,165 | 123,839 | 364,823 | 619,195 | 1,824,115 | 13,498,451 | 67,492,255 |
| -1 | -5 | -37 | -109 | -185 | -545 | -3,347 | -4,033 | -16,735 | -20,165 | -123,839 | -364,823 | -619,195 | -1,824,115 | -13,498,451 | -67,492,255 |
