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 53,160,475, 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 | 53,160,475 | |
| -1 | -53,160,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,160,475.
Example:
1 x 53,160,475 = 53,160,475
and
-1 x -53,160,475 = 53,160,475
Notice both answers equal 53,160,475
With that explanation out of the way, let's continue. Next, we take the number 53,160,475 and divide it by 2:
53,160,475 ÷ 2 = 26,580,237.5
If the quotient is a whole number, then 2 and 26,580,237.5 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 | 53,160,475 | |
| -1 | -53,160,475 |
Now, we try dividing 53,160,475 by 3:
53,160,475 ÷ 3 = 17,720,158.3333
If the quotient is a whole number, then 3 and 17,720,158.3333 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 | 53,160,475 | |
| -1 | -53,160,475 |
Let's try dividing by 4:
53,160,475 ÷ 4 = 13,290,118.75
If the quotient is a whole number, then 4 and 13,290,118.75 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 | 53,160,475 | |
| -1 | 53,160,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 59 | 115 | 295 | 575 | 1,357 | 1,475 | 1,567 | 6,785 | 7,835 | 33,925 | 36,041 | 39,175 | 92,453 | 180,205 | 462,265 | 901,025 | 2,126,419 | 2,311,325 | 10,632,095 | 53,160,475 |
| -1 | -5 | -23 | -25 | -59 | -115 | -295 | -575 | -1,357 | -1,475 | -1,567 | -6,785 | -7,835 | -33,925 | -36,041 | -39,175 | -92,453 | -180,205 | -462,265 | -901,025 | -2,126,419 | -2,311,325 | -10,632,095 | -53,160,475 |
