Badly worded question, whole numbers have a denominator of 1. However, for the sake of thoroughness, I will answer the question as I interpret it.
Step 1. Look for a common divisor. 2. 14 / 2 = 7. 24 / 2 = 12.
Step 2. Find the common denominator. 7 x 12 = 84.
Step 3. Divide by the numerator, or try to lower this fraction to lowest terms.
ERROR. No numerator was provided.
84 is as far as you can go.
A common denominator, though not the least, is 1680.
A common denominator, though not the least one, is 16*24 = 384.

LCD(24, 6) = 24.
A common denominator, though not the least one, is 6*4 = 24.
168
The least common denominator (LCD) is 1.
The least common denominator is 2 * * * * * That is totally wrong. LCD(24, 36) = 72
A common denominator, though not the least, is 240.
A common denominator, though not the least, is 1680.
It is: 24
A common denominator, though not the least one, is 24*21 = 504.
A common denominator, though not the least one, is 16*24 = 384.
A common denominator, though not the least, is 12960.
