Factors

Factors are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4.

Problem

Write a Javascript program that will store a number (eg 28, 1755, 9, etc) and outputs the following:

• If the number contains 3 as a factor, output 'Pling'.
• If the number contains 5 as a factor, output 'Plang'.
• If the number contains 7 as a factor, output 'Plong'.
• If the number does not contain 3, 5, or 7 as a factor, output the number as a string.

Examples

• When the number is 28, which has 7 as a factor.
  • The program will output "Plong".
• When the number is 1755, which has 3 and 5 as factors.
  • The program will output "PlingPlang".
• When the number is 34, which has neither 3, 5 nor 7 as a factor.
  • The program doesn't know what to make of that, so it just goes with the straightforward "34".

Bonus

• Use only 1 console.log!
