The process of finding them is the same. The difference is the function of the numbers. With an LCM, you're finding a multiple of whole numbers. With an LCD, you're finding a multiple of whole numbers that happen to be denominators.

The LCD of two fractions is the same as the LCM of their denominators.

No, the LCM of the denominators.

It is: 1260 which is also the LCM

Finding the LCM helps in the process of adding and subtracting unlike fractions.

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.

Lcd/lcm

LCM can apply to terms which don't look like fractions LCD (denominator) has to be fractions. The LCM of the denominators is the LCD.

They are practically the same except for the fact that LCD is for fractions and LCM is not.

The LCM of these numbers is 198. (LCD is just the LCM of the denominators of fractions.)

The "D" in LCD stands for denominator. The LCD is the same process as the LCM of the denominators.

Lcd = 1 Lcm = 112

The LCD or LCM is 360

The LCD or LCM is 90

the lcd is the least common denominator but the LCM is the least common multiple.
