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 45,782,569, 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 | 45,782,569 | |
| -1 | -45,782,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,782,569.
Example:
1 x 45,782,569 = 45,782,569
and
-1 x -45,782,569 = 45,782,569
Notice both answers equal 45,782,569
With that explanation out of the way, let's continue. Next, we take the number 45,782,569 and divide it by 2:
45,782,569 ÷ 2 = 22,891,284.5
If the quotient is a whole number, then 2 and 22,891,284.5 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 | 45,782,569 | |
| -1 | -45,782,569 |
Now, we try dividing 45,782,569 by 3:
45,782,569 ÷ 3 = 15,260,856.3333
If the quotient is a whole number, then 3 and 15,260,856.3333 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 | 45,782,569 | |
| -1 | -45,782,569 |
Let's try dividing by 4:
45,782,569 ÷ 4 = 11,445,642.25
If the quotient is a whole number, then 4 and 11,445,642.25 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 | 45,782,569 | |
| -1 | 45,782,569 |
If you did it right, you will end up with this table:
| 1 | 7 | 139 | 211 | 223 | 973 | 1,477 | 1,561 | 29,329 | 30,997 | 47,053 | 205,303 | 216,979 | 329,371 | 6,540,367 | 45,782,569 |
| -1 | -7 | -139 | -211 | -223 | -973 | -1,477 | -1,561 | -29,329 | -30,997 | -47,053 | -205,303 | -216,979 | -329,371 | -6,540,367 | -45,782,569 |
