## What is the HCF of 36 and 84?

The HCF of 36 and 84 is 12.

**What does LCM mean?**

least common multiple

1 : the smallest common multiple of two or more numbers. 2 : the common multiple of lowest degree of two or more polynomials.

### What is HCF formula?

The HCF formula is where the product of the LCM and HCF of the two numbers is equivalent to the product of numbers itself. The formula is: LCM (a & b) × HCF (a & b) = Product of the Numbers ( a & b)

### What is the HCF of 84?

6

The HCF of 84 and 90 is 6. To calculate the Highest common factor (HCF) of 84 and 90, we need to factor each number (factors of 84 = 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84; factors of 90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90) and choose the highest factor that exactly divides both 84 and 90, i.e., 6.

**What is the HCF of 81 and 90?**

What is the GCF of 81 and 90? The GCF of 81 and 90 is 9.

## What is HCF example?

HCF : The largest number that divides two or more numbers is the highest common factor (HCF) for those numbers. For example, consider the numbers 30 (2 x 3 x 5), 36 (2 x 2 x 3 x 3), 42 (2 x 3 x 7), 45 (3 x 3 x 5). 3 is the largest number that divides each of these numbers, and hence, is the HCF for these numbers.

## What is the formula of HCF?

HCF = Product of the common prime factors with the lowest powers. Division Method: We use Euclid’s Division Lemma( a = bq+ r.) to find the HCF of two numbers a and b. i.e. Dividend = Divisor × Quotient + Remainder.

**What is an example of LCM?**

The least common multiple can be defined as the lowest positive integer that is multiple in a given set of numbers. The least common multiple is sometimes referred to as the lowest common multiple and abbreviated as (LCM). For instance, the LCM of 2, 3, and 7 is 42 because 42 is a multiple of 2, 3, and 7.

### Why LCM is used in real life?

To split things into smaller sections. To equally distribute any number of sets of items into their largest grouping. To figure out how many people we can invite. To arrange something into rows or groups.
