Finding the prime factorisation of both denominators makes it easier to find the LCD. Simply make two columns, one for each denominator, and write the prime factors side by side. For each factor, note the larger exponent; then multiply out the list.
You need at least two numbers to find a common denominator.
That's the least common denominator or LCD.
The common denominator for a set of numbers is identified by simply multiplying the numbers together. This will not be the least common denominator, but that is not what the question is about.
You need at least two numbers to find something in common. 90 can be a common denominator of other numbers, but it can't have a common denominator all by itself.
Their least common denominator is their product. Their greatest common denominator is infinite.
Two or more fractions or mixed numbers are required to have a least common denominator.
The least common denominator of any set of numbers is always 1.
Eighty-eight is the least common denominator of these three numbers (if they aren't whole numbers; then it's just one).
The numbers 7, 3, and 2 share no common denominator. They are prime numbers.
You need at least two numbers to find something in common.
You need at least two numbers to find something in common.
The least common denominator (LCD) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least denominator for a number is itself.
