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 69,489,445, 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 | 69,489,445 | |
| -1 | -69,489,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,489,445.
Example:
1 x 69,489,445 = 69,489,445
and
-1 x -69,489,445 = 69,489,445
Notice both answers equal 69,489,445
With that explanation out of the way, let's continue. Next, we take the number 69,489,445 and divide it by 2:
69,489,445 ÷ 2 = 34,744,722.5
If the quotient is a whole number, then 2 and 34,744,722.5 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 | 69,489,445 | |
| -1 | -69,489,445 |
Now, we try dividing 69,489,445 by 3:
69,489,445 ÷ 3 = 23,163,148.3333
If the quotient is a whole number, then 3 and 23,163,148.3333 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 | 69,489,445 | |
| -1 | -69,489,445 |
Let's try dividing by 4:
69,489,445 ÷ 4 = 17,372,361.25
If the quotient is a whole number, then 4 and 17,372,361.25 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 | 69,489,445 | |
| -1 | 69,489,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 151 | 155 | 755 | 2,969 | 4,681 | 14,845 | 23,405 | 92,039 | 448,319 | 460,195 | 2,241,595 | 13,897,889 | 69,489,445 |
| -1 | -5 | -31 | -151 | -155 | -755 | -2,969 | -4,681 | -14,845 | -23,405 | -92,039 | -448,319 | -460,195 | -2,241,595 | -13,897,889 | -69,489,445 |
