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 40,310,053, 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 | 40,310,053 | |
| -1 | -40,310,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,310,053.
Example:
1 x 40,310,053 = 40,310,053
and
-1 x -40,310,053 = 40,310,053
Notice both answers equal 40,310,053
With that explanation out of the way, let's continue. Next, we take the number 40,310,053 and divide it by 2:
40,310,053 ÷ 2 = 20,155,026.5
If the quotient is a whole number, then 2 and 20,155,026.5 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 | 40,310,053 | |
| -1 | -40,310,053 |
Now, we try dividing 40,310,053 by 3:
40,310,053 ÷ 3 = 13,436,684.3333
If the quotient is a whole number, then 3 and 13,436,684.3333 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 | 40,310,053 | |
| -1 | -40,310,053 |
Let's try dividing by 4:
40,310,053 ÷ 4 = 10,077,513.25
If the quotient is a whole number, then 4 and 10,077,513.25 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 | 40,310,053 | |
| -1 | 40,310,053 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 109 | 161 | 763 | 2,297 | 2,507 | 16,079 | 17,549 | 52,831 | 250,373 | 369,817 | 1,752,611 | 5,758,579 | 40,310,053 |
| -1 | -7 | -23 | -109 | -161 | -763 | -2,297 | -2,507 | -16,079 | -17,549 | -52,831 | -250,373 | -369,817 | -1,752,611 | -5,758,579 | -40,310,053 |
