Find the LCM of the following sets of numbers: a) 8 and 6, d) 48 and 32, g) 25, 30 and 45.

$$8 = 2 \times 2 \times 2 = 2^3$$ $$6 = 2 \times 3$$

$$\text{LCM}(8, 6) = 2^3 \times 3^1 = 8 \times 3 = 24$$

The LCM of 8 and 6 is $\boxed{24}$.

$$48 = 2 \times 2 \times 2 \times 2 \times 3 = 2^4 \times 3$$ $$32 = 2 \times 2 \times 2 \times 2 \times 2 = 2^5$$

$$\text{LCM}(48, 32) = 2^5 \times 3^1 = 32 \times 3 = 96$$

The LCM of 48 and 32 is $\boxed{96}$.

$$25 = 5 \times 5 = 5^2$$ $$30 = 2 \times 3 \times 5$$ $$45 = 3 \times 3 \times 5 = 3^2 \times 5$$

$$\text{LCM}(25, 30, 45) = 2^1 \times 3^2 \times 5^2 = 2 \times 9 \times 25 = 18 \times 25 = 450$$

The LCM of 25, 30 and 45 is $\boxed{450}$.
