Because of the difference between the swings here we need to adjust the ball position to allow for this. As the iron swing is more upright, the club head will travel straighter down the target line, whereas the flatter driver swing will see more of an arc approach to the target line and therefore the ball.
For computers, see Lowest common denominator (computers) . In mathematics, the lowest common denominator or least common denominator (abbreviated LCD) is the least common multiple of the denominators of a set of fractions. It simplifies adding, subtracting, and comparing fractions.
This is the LCD for your equation. Sometimes the lowest common denominator - that is, the lowest number that has each of the existing denominators as a factor - is obvious. For example, if your expression is x/3 + 1/2 = (3x+1)/6, it's not hard to see that the smallest number with 3, 2 and 6 as a factor, is, in fact, 6.
