Subject: stack level too deep (SystemStackError)

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!
