### How do you calculate the LCD?

In order to use the greatest common factor to solve the problem, you must first multiply the two denominators together. Divide this product by the GCF. After finding the product of the two denominators, divide that product by the GCF you found previously. This number will be your least common denominator (LCD).

**What is the LCM of 32 and 33?**

The LCM of 32 and 33 is 1056.

**What is a LCM of 30?**

30 = 2 × 3 × 5. Find the prime factorization of 30. 30 = 2 × 3 × 5. LCM = 2 × 3 × 5. LCM = 30.

## What is the HCF of 33 and 44?

11

There are 2 common factors of 33 and 44, that are 1 and 11. Therefore, the greatest common factor of 33 and 44 is 11.

### What is the LCM of 32?

To find the LCM of 32 and 36 using prime factorization, we will find the prime factors, (32 = 2 × 2 × 2 × 2 × 2) and (36 = 2 × 2 × 3 × 3). LCM of 32 and 36 is the product of prime factors raised to their respective highest exponent among the numbers 32 and 36. ⇒ LCM of 32, 36 = 25 × 32 = 288.

**What is the LCD of 7 and 4?**

28

4 and 7 have 28 and 56 in common BUT the LCM would be 28 since that’s the LEAST common, or the smallest number that they would have in common.

**What is the LCD of 3 and 9?**

We can see that although 18 is present in both columns it is 9 the least in common between the two!

## What is the HCF of 45 and 30?

HCF of 45 and 30 by Prime Factorization As visible, 45 and 30 have common prime factors. Hence, the HCF of 45 and 30 is 3 × 5 = 15.

### What is the HCF of 20 30?

10

What is the HCF of 20 and 30? The HCF of 20 and 30 is 10. To calculate the Highest common factor (HCF) of 20 and 30, we need to factor each number (factors of 20 = 1, 2, 4, 5, 10, 20; factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30) and choose the highest factor that exactly divides both 20 and 30, i.e., 10.

**What is the HCF of 33 and 77?**

hcf, d (33; 77) = 11: greatest (highest) common factor (divisor), calculated.

**What is the HCF of 32?**

From the above, it is clear that 32=2×2×2×2×2 and 48=2×2×2×2×3 . We get that the highest common factors of 32 and 48 are 2×2×2×2⇒16. So, the greatest common factor of all common factors of 32 and 48 is equal to 16. So, the H.C.F of 32 and 48 is equal to 16.
