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 31,407,475, 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 | 31,407,475 | |
| -1 | -31,407,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,407,475.
Example:
1 x 31,407,475 = 31,407,475
and
-1 x -31,407,475 = 31,407,475
Notice both answers equal 31,407,475
With that explanation out of the way, let's continue. Next, we take the number 31,407,475 and divide it by 2:
31,407,475 ÷ 2 = 15,703,737.5
If the quotient is a whole number, then 2 and 15,703,737.5 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 | 31,407,475 | |
| -1 | -31,407,475 |
Now, we try dividing 31,407,475 by 3:
31,407,475 ÷ 3 = 10,469,158.3333
If the quotient is a whole number, then 3 and 10,469,158.3333 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 | 31,407,475 | |
| -1 | -31,407,475 |
Let's try dividing by 4:
31,407,475 ÷ 4 = 7,851,868.75
If the quotient is a whole number, then 4 and 7,851,868.75 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 | 31,407,475 | |
| -1 | 31,407,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 25 | 55 | 95 | 209 | 275 | 475 | 1,045 | 5,225 | 6,011 | 30,055 | 66,121 | 114,209 | 150,275 | 330,605 | 571,045 | 1,256,299 | 1,653,025 | 2,855,225 | 6,281,495 | 31,407,475 |
| -1 | -5 | -11 | -19 | -25 | -55 | -95 | -209 | -275 | -475 | -1,045 | -5,225 | -6,011 | -30,055 | -66,121 | -114,209 | -150,275 | -330,605 | -571,045 | -1,256,299 | -1,653,025 | -2,855,225 | -6,281,495 | -31,407,475 |
