Question

7.least common denominator

Answer 1

Least Common Denominator = 28

Step-by-step explanation:

To find the Least Common Denominator, we take the following steps.

First, we find the prime factorization of each integer.

`\begin{gathered} 7=7^1 \\ 4=2^2 \end{gathered}`

Next, we find the largest power that appears in the prime factorization.

The largest power of 2 is 2^2 and the largest power of 7 is 7^1; therefore, the least common denominator is

7 * 4 = 28
