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 79,438,337, 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 | 79,438,337 | |
| -1 | -79,438,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 79,438,337.
Example:
1 x 79,438,337 = 79,438,337
and
-1 x -79,438,337 = 79,438,337
Notice both answers equal 79,438,337
With that explanation out of the way, let's continue. Next, we take the number 79,438,337 and divide it by 2:
79,438,337 ÷ 2 = 39,719,168.5
If the quotient is a whole number, then 2 and 39,719,168.5 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 | 79,438,337 | |
| -1 | -79,438,337 |
Now, we try dividing 79,438,337 by 3:
79,438,337 ÷ 3 = 26,479,445.6667
If the quotient is a whole number, then 3 and 26,479,445.6667 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 | 79,438,337 | |
| -1 | -79,438,337 |
Let's try dividing by 4:
79,438,337 ÷ 4 = 19,859,584.25
If the quotient is a whole number, then 4 and 19,859,584.25 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 | 79,438,337 | |
| -1 | 79,438,337 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 31 | 277 | 319 | 341 | 841 | 899 | 3,047 | 8,033 | 8,587 | 9,251 | 9,889 | 26,071 | 88,363 | 94,457 | 232,957 | 249,023 | 286,781 | 2,562,527 | 2,739,253 | 7,221,667 | 79,438,337 |
| -1 | -11 | -29 | -31 | -277 | -319 | -341 | -841 | -899 | -3,047 | -8,033 | -8,587 | -9,251 | -9,889 | -26,071 | -88,363 | -94,457 | -232,957 | -249,023 | -286,781 | -2,562,527 | -2,739,253 | -7,221,667 | -79,438,337 |
