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 70,914,415, 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 | 70,914,415 | |
| -1 | -70,914,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,914,415.
Example:
1 x 70,914,415 = 70,914,415
and
-1 x -70,914,415 = 70,914,415
Notice both answers equal 70,914,415
With that explanation out of the way, let's continue. Next, we take the number 70,914,415 and divide it by 2:
70,914,415 ÷ 2 = 35,457,207.5
If the quotient is a whole number, then 2 and 35,457,207.5 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 | 70,914,415 | |
| -1 | -70,914,415 |
Now, we try dividing 70,914,415 by 3:
70,914,415 ÷ 3 = 23,638,138.3333
If the quotient is a whole number, then 3 and 23,638,138.3333 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 | 70,914,415 | |
| -1 | -70,914,415 |
Let's try dividing by 4:
70,914,415 ÷ 4 = 17,728,603.75
If the quotient is a whole number, then 4 and 17,728,603.75 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 | 70,914,415 | |
| -1 | 70,914,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 99,181 | 495,905 | 1,090,991 | 1,289,353 | 5,454,955 | 6,446,765 | 14,182,883 | 70,914,415 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -99,181 | -495,905 | -1,090,991 | -1,289,353 | -5,454,955 | -6,446,765 | -14,182,883 | -70,914,415 |
