one twelfth
That's the least common denominator or LCD.
The least common denominator.
4/7 and 3/5 have an LCD of 35 since they 7 and 5 have no common factors.
To find the least common denominator of 1/3 and 1/4, we need to determine the smallest multiple that both denominators (3 and 4) have in common. The least common denominator is the least common multiple (LCM) of the denominators. The LCM of 3 and 4 is 12, so the least common denominator of 1/3 and 1/4 is 12.
The least common multiple of two or more denominators is known as the least common denominator, or LCD.
