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 69,392,905, 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 | 69,392,905 | |
| -1 | -69,392,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,392,905.
Example:
1 x 69,392,905 = 69,392,905
and
-1 x -69,392,905 = 69,392,905
Notice both answers equal 69,392,905
With that explanation out of the way, let's continue. Next, we take the number 69,392,905 and divide it by 2:
69,392,905 ÷ 2 = 34,696,452.5
If the quotient is a whole number, then 2 and 34,696,452.5 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 | 69,392,905 | |
| -1 | -69,392,905 |
Now, we try dividing 69,392,905 by 3:
69,392,905 ÷ 3 = 23,130,968.3333
If the quotient is a whole number, then 3 and 23,130,968.3333 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 | 69,392,905 | |
| -1 | -69,392,905 |
Let's try dividing by 4:
69,392,905 ÷ 4 = 17,348,226.25
If the quotient is a whole number, then 4 and 17,348,226.25 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 | 69,392,905 | |
| -1 | 69,392,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 335 | 359 | 577 | 1,795 | 2,885 | 24,053 | 38,659 | 120,265 | 193,295 | 207,143 | 1,035,715 | 13,878,581 | 69,392,905 |
| -1 | -5 | -67 | -335 | -359 | -577 | -1,795 | -2,885 | -24,053 | -38,659 | -120,265 | -193,295 | -207,143 | -1,035,715 | -13,878,581 | -69,392,905 |
