The sum of all the factors of 27 is the 5th multiple of a number. What is the number? Please help me.......​

Sagot :

Answer:

[tex]\displaystyle 8[/tex]

Step-by-step explanation:

List all the factors of twenty-seven, then sum them up:

[tex]\displaystyle 1, 3, 9, 27; 40 = 27 + 3 + 9 + 1[/tex]

Now, the clue tells you that forty is the fifth multiple of some quantity, so divide by five to get your result, and it MUST be a whole number, or elce we have no solution here:

[tex]\displaystyle 8 = \frac{40}{5}[/tex]

Eight is the quantity you are looking for, and sinse it is a whole number, it is valid.
