When writing a code to find the factor of a given number, i ran into the

following error message:

“factor.rb:48: parse error, unexpected kEND, expecting $”

I was hoping someone could shed light on the problem. Heres the code:

def isprime testNum

testWith = 2

run = 1

while testNum > testWith and run == 1

prime = testNum % testWith

if prime != 0

testWith = testWith + 1

else

run = 2

end

end

```
if prime != 0
return true
else
return false
end
```

end

def factor toFactor

factored = false

numbers = Array.new

numbers.push toFactor

testWith = 2

while factored == false and numbers.last > testWith

test = numbers.last

isFactor = numbers.last%testWith

if isFactor == 0

numbers.pop

numbers.push(testWith)

numbers.push(test/testWith)

factored = true

else

testWith = testWith + 1

end

end

```
eval = numbers.last
if isprime(eval) == false
numbers.pop
add = factor(eval)
numbers.push(add)
end
end
numbers
```

end

f = factor(100)

puts f.join(’ x ')

Note: subsituting " eval = numbers.last" for "numbers.each do |eval|

"avoids the error.

Please Help!
