90 is your common denominator.
Eighty-eight is the least common denominator of these three numbers (if they aren't whole numbers; then it's just one).
Since all three numbers are prime and prime numbers have no other factors than themselves, their Least Common Denominator is 1.
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions. Even if you converted your numbers (x) to their fraction equivalents (x/1), the LCD will always be 1.
The fraction becomes smaller: provided the denominator was positive.
You can do this by multiplying both the numerator and denominator by a common number. For example, six tenths is an equivalent fraction because the numerator and denominator were both multiplied by 2.
The common denominator of any two or more whole numbers, such as 13 and 12, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
The LCM of these three numbers is 90.
The LCD for the given three numbers is 60
The LCD of the given three numbers is 18
The LCD for the given three numbers is 36
A common denominator is 32.
The LCD of the given three numbers is 4692
The LCD of the given three numbers is 110
The LCD of the given three numbers is 714
You look for common factors between numerator and denominator, and then divide both numerator and denominator by that common factor. For example, if you have the fraction 40/60, you immediately see that both numbers are multilples of 10. Dividing both by 10, you get 4/6. If you continue looking for common factors, you find that both are even, so you divide both by 2. The result in this case is 2/3.
12 is the denominator of 3/12 (three twelfths)
A common denominator is A*B*C. There is not enough information to determine whether or not it is the least such number: that will depend on whether or not the three numbers are co-prime.
The reciprocal of a fraction is basically the same fraction flip-flopped. So the numerator becomes the denominator, and the denominator becomes the denominator. So for seven over three, the reciprocal would be three over seven.
Least number is 120 if the three numbers are the denominators of fractions
The LCD or LCM of the given three numbers is: 326,977,440
Answer: 30 If those numbers are denominators, the least common denominator is the least common multiple of the three. In this case, 30 is the LCM of 6, 10 and 15, so 30 is the least common denominator.
The common denominator is 4
The least common denominator of three fourths and five sixths is twelve.
three, because for one third three was the denominator , and for one sixth the denominator was devisable by three.
