下列Python代码用于求解两个正整数的最大公约数，相关说法中错误的是(    )。

def gcd0(big, small):
	if big < small:
		big, small = small, big
	if big % small == 0:
		return small
	return gcd0(small, big % small)

def gcd1(big,small):
	if big < small:
		big, small = small, big
	for i in range(small, 0, -1):
		if big % i == 0 and small % i == 0:
			return i
print(gcd0(48,24))
print(gcd1(36,24))
