Answer:
<h2>12a</h2>Step-by-step explanation:
The least common divisor refers to the smallest common number that multiplies all of them, so in this case, the Least Common Factor is
4 6 | 2
2 3 | 2
1 3 | 3
1 1
So, the LCD is , and the variable would be just <em>a</em>, because it's already the least possible one.
Theferefore, the LCD is 12a
In the process to obtain the LCD we just separated each number in their prime factors.

Answer:
1 and - 1
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope ( gradient ) )
y = x ← is in this form
with gradient m = 1
Parallel lines have equal gradients
Then the gradients of lines parallel to the given line is 1
Given a line with gradient m then the gradient of a line perpendicular to it is
= -
= -
= - 1
Then the gradients of lines perpendicular to this line is - 1
