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 142,453,025, 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 | 142,453,025 | |
| -1 | -142,453,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,453,025.
Example:
1 x 142,453,025 = 142,453,025
and
-1 x -142,453,025 = 142,453,025
Notice both answers equal 142,453,025
With that explanation out of the way, let's continue. Next, we take the number 142,453,025 and divide it by 2:
142,453,025 ÷ 2 = 71,226,512.5
If the quotient is a whole number, then 2 and 71,226,512.5 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 | 142,453,025 | |
| -1 | -142,453,025 |
Now, we try dividing 142,453,025 by 3:
142,453,025 ÷ 3 = 47,484,341.6667
If the quotient is a whole number, then 3 and 47,484,341.6667 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 | 142,453,025 | |
| -1 | -142,453,025 |
Let's try dividing by 4:
142,453,025 ÷ 4 = 35,613,256.25
If the quotient is a whole number, then 4 and 35,613,256.25 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 | 142,453,025 | |
| -1 | 142,453,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 715 | 3,575 | 39,847 | 199,235 | 438,317 | 518,011 | 996,175 | 2,191,585 | 2,590,055 | 5,698,121 | 10,957,925 | 12,950,275 | 28,490,605 | 142,453,025 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -715 | -3,575 | -39,847 | -199,235 | -438,317 | -518,011 | -996,175 | -2,191,585 | -2,590,055 | -5,698,121 | -10,957,925 | -12,950,275 | -28,490,605 | -142,453,025 |
