The least common multiple (LCM) of 6a and 8a is the smallest number that is divisible by both 6a and 8a. To find the LCM, we need to first find the prime factors of each number. The prime factors of 6a are 2 x 3 x a, and the prime factors of 8a are 2 x 2 x 2 x a. The LCM is the product of all the unique prime factors with the highest power, so the LCM of 6a and 8a is 2 x 2 x 2 x 3 x a, which simplifies to 24a.
6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
4a+8a = 12a 12a divided by 2 = 6a

Do the numbers first. The LCM of 6 and 8 is 24. Choose the highest of the powers. The LCM is 24a^3
6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
8a-a-a = 6a
4a+8a = 12a 12a divided by 2 = 6a
a+6a+a=8a
It is 6a.
The GCF of 6a^2 and 8a is 2a.
