141 point Which is the least common denominator of $\frac{2}{14}, \frac{3}{10}$, and $\frac{1}{2}$ ? The answer is type your answer...

Step 1 ：The least common denominator (LCD) of a set of fractions is the least common multiple (LCM) of the denominators of the fractions. In this case, we need to find the LCM of 14, 10, and 2.

Step 2 ：Let's denote the denominators as an array: denominators = [14, 10, 2]

Step 3 ：By calculating the least common multiple of these numbers, we find that the least common denominator (LCD) is 70.

Step 4 ：Hence, the least common denominator of the fractions \(\frac{2}{14}, \frac{3}{10}\), and \(\frac{1}{2}\) is 70.

Step 5 ：Final Answer: The least common denominator of the fractions \(\frac{2}{14}, \frac{3}{10}\), and \(\frac{1}{2}\) is \(\boxed{70}\).
