The common denominator of any two or more whole numbers will always be 1.

LCD(14, 19, 15) = 3990

The Common Denominator For 9 and 19 Is 177

20 is.

The LCD of 9/20 and 19/46 is 460.

A common denominator is 209, as is any multiple of 209.

As far as simplify meaning finding a smaller denominator, the answer is no. The only common factor between 19 and 15 is 1, so the fraction cannot be reduced, but it is an improper fraction, so you could turn it into a mixed number: 19/15 = 1 4/15.

It is 12*19 = 228.

The greatest common denominator of any set of numbers is infinite.

To find which of two fractions is greater, first find a common denominator. The fraction with the larger numerator is the greater fraction. Note that it is not necessary to multiply the terms of the common denominator; it is only the numerator that must be worked out.4/15 = (4 x 19)/(19 x 15) = 76/(19 x 15)5/19 = (5 x 15)/(19 x 15) = 75/(19 x 15)This shows that 4/15 is greater than 5/19.

LCD(20, 19) = 380.

The LCD for 19 and 2 is 38

The LCD for 19 and 3 is 57

If two fractions share an equal denominator, you can simply add the top, so 15 + 4 = 19, so therefore = 19/25

The common denominator is usually the Lowest (or Least) Common Multiple of the numbers involved. Where two numbers have no common factors then the LCM is simply the product of those numbers. As 19 is a prime number and has no factors in common with 18 then the common denominator is 18 x 19 = 342.

It is 76

lcd(8, 19) = 152.

19 is prime, so multiply 19 by 112.

The answer is 19/100. 19 is the numerator and 100 is the denominator. You would write the numerator over the denominator, separating them with a horizontal line in the middle.
