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 1,876,225, 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 | 1,876,225 | |
| -1 | -1,876,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,876,225.
Example:
1 x 1,876,225 = 1,876,225
and
-1 x -1,876,225 = 1,876,225
Notice both answers equal 1,876,225
With that explanation out of the way, let's continue. Next, we take the number 1,876,225 and divide it by 2:
1,876,225 ÷ 2 = 938,112.5
If the quotient is a whole number, then 2 and 938,112.5 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 | 1,876,225 | |
| -1 | -1,876,225 |
Now, we try dividing 1,876,225 by 3:
1,876,225 ÷ 3 = 625,408.3333
If the quotient is a whole number, then 3 and 625,408.3333 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 | 1,876,225 | |
| -1 | -1,876,225 |
Let's try dividing by 4:
1,876,225 ÷ 4 = 469,056.25
If the quotient is a whole number, then 4 and 469,056.25 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 | 1,876,225 | |
| -1 | 1,876,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 25 | 65 | 115 | 251 | 299 | 325 | 575 | 1,255 | 1,495 | 3,263 | 5,773 | 6,275 | 7,475 | 16,315 | 28,865 | 75,049 | 81,575 | 144,325 | 375,245 | 1,876,225 |
| -1 | -5 | -13 | -23 | -25 | -65 | -115 | -251 | -299 | -325 | -575 | -1,255 | -1,495 | -3,263 | -5,773 | -6,275 | -7,475 | -16,315 | -28,865 | -75,049 | -81,575 | -144,325 | -375,245 | -1,876,225 |
