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 40,646,053, 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 | 40,646,053 | |
| -1 | -40,646,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,646,053.
Example:
1 x 40,646,053 = 40,646,053
and
-1 x -40,646,053 = 40,646,053
Notice both answers equal 40,646,053
With that explanation out of the way, let's continue. Next, we take the number 40,646,053 and divide it by 2:
40,646,053 ÷ 2 = 20,323,026.5
If the quotient is a whole number, then 2 and 20,323,026.5 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 | 40,646,053 | |
| -1 | -40,646,053 |
Now, we try dividing 40,646,053 by 3:
40,646,053 ÷ 3 = 13,548,684.3333
If the quotient is a whole number, then 3 and 13,548,684.3333 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 | 40,646,053 | |
| -1 | -40,646,053 |
Let's try dividing by 4:
40,646,053 ÷ 4 = 10,161,513.25
If the quotient is a whole number, then 4 and 10,161,513.25 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 | 40,646,053 | |
| -1 | 40,646,053 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 79 | 217 | 553 | 2,371 | 2,449 | 16,597 | 17,143 | 73,501 | 187,309 | 514,507 | 1,311,163 | 5,806,579 | 40,646,053 |
| -1 | -7 | -31 | -79 | -217 | -553 | -2,371 | -2,449 | -16,597 | -17,143 | -73,501 | -187,309 | -514,507 | -1,311,163 | -5,806,579 | -40,646,053 |
