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 53,455,003, 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 | 53,455,003 | |
| -1 | -53,455,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,455,003.
Example:
1 x 53,455,003 = 53,455,003
and
-1 x -53,455,003 = 53,455,003
Notice both answers equal 53,455,003
With that explanation out of the way, let's continue. Next, we take the number 53,455,003 and divide it by 2:
53,455,003 ÷ 2 = 26,727,501.5
If the quotient is a whole number, then 2 and 26,727,501.5 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 | 53,455,003 | |
| -1 | -53,455,003 |
Now, we try dividing 53,455,003 by 3:
53,455,003 ÷ 3 = 17,818,334.3333
If the quotient is a whole number, then 3 and 17,818,334.3333 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 | 53,455,003 | |
| -1 | -53,455,003 |
Let's try dividing by 4:
53,455,003 ÷ 4 = 13,363,750.75
If the quotient is a whole number, then 4 and 13,363,750.75 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 | 53,455,003 | |
| -1 | 53,455,003 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 347 | 373 | 413 | 2,429 | 2,611 | 20,473 | 22,007 | 129,431 | 143,311 | 154,049 | 906,017 | 7,636,429 | 53,455,003 |
| -1 | -7 | -59 | -347 | -373 | -413 | -2,429 | -2,611 | -20,473 | -22,007 | -129,431 | -143,311 | -154,049 | -906,017 | -7,636,429 | -53,455,003 |
