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 70,260,715, 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 | 70,260,715 | |
| -1 | -70,260,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,260,715.
Example:
1 x 70,260,715 = 70,260,715
and
-1 x -70,260,715 = 70,260,715
Notice both answers equal 70,260,715
With that explanation out of the way, let's continue. Next, we take the number 70,260,715 and divide it by 2:
70,260,715 ÷ 2 = 35,130,357.5
If the quotient is a whole number, then 2 and 35,130,357.5 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 | 70,260,715 | |
| -1 | -70,260,715 |
Now, we try dividing 70,260,715 by 3:
70,260,715 ÷ 3 = 23,420,238.3333
If the quotient is a whole number, then 3 and 23,420,238.3333 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 | 70,260,715 | |
| -1 | -70,260,715 |
Let's try dividing by 4:
70,260,715 ÷ 4 = 17,565,178.75
If the quotient is a whole number, then 4 and 17,565,178.75 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 | 70,260,715 | |
| -1 | 70,260,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 61 | 305 | 427 | 2,135 | 32,909 | 164,545 | 230,363 | 1,151,815 | 2,007,449 | 10,037,245 | 14,052,143 | 70,260,715 |
| -1 | -5 | -7 | -35 | -61 | -305 | -427 | -2,135 | -32,909 | -164,545 | -230,363 | -1,151,815 | -2,007,449 | -10,037,245 | -14,052,143 | -70,260,715 |
