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 69,125,995, 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 | 69,125,995 | |
| -1 | -69,125,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,125,995.
Example:
1 x 69,125,995 = 69,125,995
and
-1 x -69,125,995 = 69,125,995
Notice both answers equal 69,125,995
With that explanation out of the way, let's continue. Next, we take the number 69,125,995 and divide it by 2:
69,125,995 ÷ 2 = 34,562,997.5
If the quotient is a whole number, then 2 and 34,562,997.5 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 | 69,125,995 | |
| -1 | -69,125,995 |
Now, we try dividing 69,125,995 by 3:
69,125,995 ÷ 3 = 23,041,998.3333
If the quotient is a whole number, then 3 and 23,041,998.3333 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 | 69,125,995 | |
| -1 | -69,125,995 |
Let's try dividing by 4:
69,125,995 ÷ 4 = 17,281,498.75
If the quotient is a whole number, then 4 and 17,281,498.75 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 | 69,125,995 | |
| -1 | 69,125,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 841 | 967 | 2,465 | 4,205 | 4,835 | 14,297 | 16,439 | 28,043 | 71,485 | 82,195 | 140,215 | 476,731 | 813,247 | 2,383,655 | 4,066,235 | 13,825,199 | 69,125,995 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -841 | -967 | -2,465 | -4,205 | -4,835 | -14,297 | -16,439 | -28,043 | -71,485 | -82,195 | -140,215 | -476,731 | -813,247 | -2,383,655 | -4,066,235 | -13,825,199 | -69,125,995 |
