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 53,430,377, 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 | 53,430,377 | |
| -1 | -53,430,377 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,430,377.
Example:
1 x 53,430,377 = 53,430,377
and
-1 x -53,430,377 = 53,430,377
Notice both answers equal 53,430,377
With that explanation out of the way, let's continue. Next, we take the number 53,430,377 and divide it by 2:
53,430,377 ÷ 2 = 26,715,188.5
If the quotient is a whole number, then 2 and 26,715,188.5 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 | 53,430,377 | |
| -1 | -53,430,377 |
Now, we try dividing 53,430,377 by 3:
53,430,377 ÷ 3 = 17,810,125.6667
If the quotient is a whole number, then 3 and 17,810,125.6667 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 | 53,430,377 | |
| -1 | -53,430,377 |
Let's try dividing by 4:
53,430,377 ÷ 4 = 13,357,594.25
If the quotient is a whole number, then 4 and 13,357,594.25 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 | 53,430,377 | |
| -1 | 53,430,377 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 53,377 | 373,639 | 587,147 | 693,901 | 4,110,029 | 4,857,307 | 7,632,911 | 53,430,377 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -53,377 | -373,639 | -587,147 | -693,901 | -4,110,029 | -4,857,307 | -7,632,911 | -53,430,377 |
