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 53,157,145, 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 | 53,157,145 | |
| -1 | -53,157,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,157,145.
Example:
1 x 53,157,145 = 53,157,145
and
-1 x -53,157,145 = 53,157,145
Notice both answers equal 53,157,145
With that explanation out of the way, let's continue. Next, we take the number 53,157,145 and divide it by 2:
53,157,145 ÷ 2 = 26,578,572.5
If the quotient is a whole number, then 2 and 26,578,572.5 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 | 53,157,145 | |
| -1 | -53,157,145 |
Now, we try dividing 53,157,145 by 3:
53,157,145 ÷ 3 = 17,719,048.3333
If the quotient is a whole number, then 3 and 17,719,048.3333 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 | 53,157,145 | |
| -1 | -53,157,145 |
Let's try dividing by 4:
53,157,145 ÷ 4 = 13,289,286.25
If the quotient is a whole number, then 4 and 13,289,286.25 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 | 53,157,145 | |
| -1 | 53,157,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 53 | 145 | 265 | 1,537 | 6,917 | 7,685 | 34,585 | 200,593 | 366,601 | 1,002,965 | 1,833,005 | 10,631,429 | 53,157,145 |
| -1 | -5 | -29 | -53 | -145 | -265 | -1,537 | -6,917 | -7,685 | -34,585 | -200,593 | -366,601 | -1,002,965 | -1,833,005 | -10,631,429 | -53,157,145 |
