## What is the LCD of 6 and 9?

We see that the numbers 18 and 36 are both common multiples of 6 and 9. The least common multiple is the smallest which is 18.

## What is the LCD of 1 3 and 2 7?

Therefore, the least common denominator ( LCD ) is 21.

## What is the LCD of 12 and 9?

Your common denominator would be 36. Another way to find this would be to multiply each fraction by the other fractions denominator.

## Is LCD and LCM the same?

The LCD and the LCM require the same math process: Finding a common multiple of two (or more) numbers. The only difference between LCD and LCM is that the LCD is the LCM in the denominator of a fraction. So, one could say that least common denominators are a special case of least common multiples.

## What is the LCD of 7 and 9?

63 is the least common multiple of 7 and 9.

## What is the LCD of 4 and 9?

Least common multiple ( LCM) of 4 and 9 is 36.

## What is the GCF of 6 and 9?

What is the Greatest Common Factor of 6 and 9? Greatest common factor (GCF ) of 6 and 9 is 3. We will now calculate the prime factors of 6 and 9, than find the greatest common factor ( greatest common divisor (gcd )) of the numbers by matching the biggest common factor of 6 and 9.

## What is the LCD of 7 and 3?

Least common multiple ( LCM ) of 3 and 7 is 21.

## What is the LCD of 7 and 4?

Answer: LCM of 4 and 7 is 28.

## What is the LCD of 8 and 3?

The least common multiple of 3 and 8 is 24.

## What is the GCF of 12 and 9?

The biggest common factor number is the GCF number. So the greatest common factor 9 and 12 is 3.
