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 402,110,657, 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 | 402,110,657 | |
| -1 | -402,110,657 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 402,110,657.
Example:
1 x 402,110,657 = 402,110,657
and
-1 x -402,110,657 = 402,110,657
Notice both answers equal 402,110,657
With that explanation out of the way, let's continue. Next, we take the number 402,110,657 and divide it by 2:
402,110,657 ÷ 2 = 201,055,328.5
If the quotient is a whole number, then 2 and 201,055,328.5 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 | 402,110,657 | |
| -1 | -402,110,657 |
Now, we try dividing 402,110,657 by 3:
402,110,657 ÷ 3 = 134,036,885.6667
If the quotient is a whole number, then 3 and 134,036,885.6667 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 | 402,110,657 | |
| -1 | -402,110,657 |
Let's try dividing by 4:
402,110,657 ÷ 4 = 100,527,664.25
If the quotient is a whole number, then 4 and 100,527,664.25 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 | 402,110,657 | |
| -1 | 402,110,657 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 131 | 169 | 443 | 533 | 1,703 | 5,371 | 5,759 | 6,929 | 18,163 | 22,139 | 58,033 | 69,823 | 74,867 | 236,119 | 754,429 | 907,699 | 2,379,353 | 3,069,547 | 9,807,577 | 30,931,589 | 402,110,657 |
| -1 | -13 | -41 | -131 | -169 | -443 | -533 | -1,703 | -5,371 | -5,759 | -6,929 | -18,163 | -22,139 | -58,033 | -69,823 | -74,867 | -236,119 | -754,429 | -907,699 | -2,379,353 | -3,069,547 | -9,807,577 | -30,931,589 | -402,110,657 |
