What is the difference between lcd and LCM?

Answer 1

LCD is where you find the LCM of the denominator of a fraction..

Least Common Multiple(LCM) works this way:

the LCM of 3, 6, 9 is:

3=3, 6, 9, 12, 15, 18, 21, 24, 27, 30;

6=12, 18, 24, 30, 36, 42, 48, 54, 60;

9=9, 18, 27, 36, 45, 54, 63, 72, 81, 90;

18 is the LCM since 18 is the smallest multiple of the three numbers

so that's it.. LCD works this way:

it is used in fractions.. example:

the LCD of:

1/3

2/6

1453/9

is:

the LCM of the denominator of the three numbers is 18.

(18/9) x 1453 = n.

(18/6) x 2 = o.

(18/3) x 1 = p.

n + o + p = LCD/18..

Answer 2

the LCM and lcd are both math terms. the LCD is Least Common Denominator. the LCM is the Least Common Multiple. glad i could help,

kellers 9er 9er!

Answer 3

The function of the numbers in question. For the LCM, you are finding a whole number. For the LCD, you are finding a denominator. The process is the same.
