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 77,374,465, 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 | 77,374,465 | |
| -1 | -77,374,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,374,465.
Example:
1 x 77,374,465 = 77,374,465
and
-1 x -77,374,465 = 77,374,465
Notice both answers equal 77,374,465
With that explanation out of the way, let's continue. Next, we take the number 77,374,465 and divide it by 2:
77,374,465 ÷ 2 = 38,687,232.5
If the quotient is a whole number, then 2 and 38,687,232.5 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 | 77,374,465 | |
| -1 | -77,374,465 |
Now, we try dividing 77,374,465 by 3:
77,374,465 ÷ 3 = 25,791,488.3333
If the quotient is a whole number, then 3 and 25,791,488.3333 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 | 77,374,465 | |
| -1 | -77,374,465 |
Let's try dividing by 4:
77,374,465 ÷ 4 = 19,343,616.25
If the quotient is a whole number, then 4 and 19,343,616.25 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 | 77,374,465 | |
| -1 | 77,374,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 76,231 | 381,155 | 533,617 | 2,210,699 | 2,668,085 | 11,053,495 | 15,474,893 | 77,374,465 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -76,231 | -381,155 | -533,617 | -2,210,699 | -2,668,085 | -11,053,495 | -15,474,893 | -77,374,465 |
