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 69,973,757, 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 | 69,973,757 | |
| -1 | -69,973,757 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,973,757.
Example:
1 x 69,973,757 = 69,973,757
and
-1 x -69,973,757 = 69,973,757
Notice both answers equal 69,973,757
With that explanation out of the way, let's continue. Next, we take the number 69,973,757 and divide it by 2:
69,973,757 ÷ 2 = 34,986,878.5
If the quotient is a whole number, then 2 and 34,986,878.5 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 | 69,973,757 | |
| -1 | -69,973,757 |
Now, we try dividing 69,973,757 by 3:
69,973,757 ÷ 3 = 23,324,585.6667
If the quotient is a whole number, then 3 and 23,324,585.6667 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 | 69,973,757 | |
| -1 | -69,973,757 |
Let's try dividing by 4:
69,973,757 ÷ 4 = 17,493,439.25
If the quotient is a whole number, then 4 and 17,493,439.25 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 | 69,973,757 | |
| -1 | 69,973,757 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 287 | 479 | 509 | 3,353 | 3,563 | 19,639 | 20,869 | 137,473 | 146,083 | 243,811 | 1,706,677 | 9,996,251 | 69,973,757 |
| -1 | -7 | -41 | -287 | -479 | -509 | -3,353 | -3,563 | -19,639 | -20,869 | -137,473 | -146,083 | -243,811 | -1,706,677 | -9,996,251 | -69,973,757 |
