Solve the following python programming problem given the following code:
def gcd_terms(terms, isprimitive = False, clear = True, fraction = True) : 
    'Compute the GCD of ``terms`` and put them together.

    ``terms`` can be an expression or a non-Basic sequence of expressions
    which will be handled as though they are terms from a sum.

    If ``isprimitive`` is True the _gcd_terms will not run the primitive
    method on the terms.

    ``clear`` controls the removal of integers from the denominator of an Add
    expression. When True (default), all numerical denominator will be cleared;
    when False the denominators will be cleared only if all terms had numerical
    denominators other than 1.

    ``fraction``, when True (default), will put the expression over a common
    denominator.

    Examples
    ========

    >>> from sympy.core import gcd_terms
    >>> from sympy.abc import x, y

    >>> gcd_terms((x + 1)**2*y + (x + 1)*y**2)
    y*(x + 1)*(x + y + 1)
    >>> gcd_terms(x/2 + 1)
    (x + 2)/2
    >>> gcd_terms(x/2 + 1, clear=False)
    x/2 + 1
    >>> gcd_terms(x/2 + y/2, clear=False)
    (x + y)/2
    >>> gcd_terms(x/2 + 1/x)
    (x**2 + 2)/(2*x)
    >>> gcd_terms(x/2 + 1/x, fraction=False)
    (x + 2/x)/2
    >>> gcd_terms(x/2 + 1/x, fraction=False, clear=False)
    x/2 + 1/x

    >>> gcd_terms(x/2/y + 1/x/y)
    (x**2 + 2)/(2*x*y)
    >>> gcd_terms(x/2/y + 1/x/y, clear=False)
    (x**2/2 + 1)/(x*y)
    >>> gcd_terms(x/2/y + 1/x/y, clear=False, fraction=False)
    (x/2 + 1/x)/y

    The ``clear`` flag was ignored in this case because the returned
    expression was a rational expression, not a simple sum.
