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 69,895,405, 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 | 69,895,405 | |
| -1 | -69,895,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,895,405.
Example:
1 x 69,895,405 = 69,895,405
and
-1 x -69,895,405 = 69,895,405
Notice both answers equal 69,895,405
With that explanation out of the way, let's continue. Next, we take the number 69,895,405 and divide it by 2:
69,895,405 ÷ 2 = 34,947,702.5
If the quotient is a whole number, then 2 and 34,947,702.5 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 | 69,895,405 | |
| -1 | -69,895,405 |
Now, we try dividing 69,895,405 by 3:
69,895,405 ÷ 3 = 23,298,468.3333
If the quotient is a whole number, then 3 and 23,298,468.3333 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 | 69,895,405 | |
| -1 | -69,895,405 |
Let's try dividing by 4:
69,895,405 ÷ 4 = 17,473,851.25
If the quotient is a whole number, then 4 and 17,473,851.25 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 | 69,895,405 | |
| -1 | 69,895,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 67 | 185 | 335 | 2,479 | 5,639 | 12,395 | 28,195 | 208,643 | 377,813 | 1,043,215 | 1,889,065 | 13,979,081 | 69,895,405 |
| -1 | -5 | -37 | -67 | -185 | -335 | -2,479 | -5,639 | -12,395 | -28,195 | -208,643 | -377,813 | -1,043,215 | -1,889,065 | -13,979,081 | -69,895,405 |
