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 53,251,325, 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 | 53,251,325 | |
| -1 | -53,251,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,251,325.
Example:
1 x 53,251,325 = 53,251,325
and
-1 x -53,251,325 = 53,251,325
Notice both answers equal 53,251,325
With that explanation out of the way, let's continue. Next, we take the number 53,251,325 and divide it by 2:
53,251,325 ÷ 2 = 26,625,662.5
If the quotient is a whole number, then 2 and 26,625,662.5 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 | 53,251,325 | |
| -1 | -53,251,325 |
Now, we try dividing 53,251,325 by 3:
53,251,325 ÷ 3 = 17,750,441.6667
If the quotient is a whole number, then 3 and 17,750,441.6667 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 | 53,251,325 | |
| -1 | -53,251,325 |
Let's try dividing by 4:
53,251,325 ÷ 4 = 13,312,831.25
If the quotient is a whole number, then 4 and 13,312,831.25 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 | 53,251,325 | |
| -1 | 53,251,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 37 | 115 | 185 | 575 | 851 | 925 | 2,503 | 4,255 | 12,515 | 21,275 | 57,569 | 62,575 | 92,611 | 287,845 | 463,055 | 1,439,225 | 2,130,053 | 2,315,275 | 10,650,265 | 53,251,325 |
| -1 | -5 | -23 | -25 | -37 | -115 | -185 | -575 | -851 | -925 | -2,503 | -4,255 | -12,515 | -21,275 | -57,569 | -62,575 | -92,611 | -287,845 | -463,055 | -1,439,225 | -2,130,053 | -2,315,275 | -10,650,265 | -53,251,325 |
