# What is the GCF and LCM of 3 and 8?

## What is the GCF and LCM of 3 and 8?

Example 3: Find the GCF of 3 and 8, if their LCM is 24. Therefore, the greatest common factor of 3 and 8 is 1.

### How do you find the LCM of 8?

Multiples of 8 are: 8, 16, 24, 32, 40.. So 24 is the least common multiple (I can’t find a smaller one!)

How do you solve for LCM?

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

What is the HCF of 3 and 8?

The HCF of 3 and 8 is 1. To calculate the Highest common factor (HCF) of 3 and 8, we need to factor each number (factors of 3 = 1, 3; factors of 8 = 1, 2, 4, 8) and choose the highest factor that exactly divides both 3 and 8, i.e., 1.

## What is the LCM of 8 and 6?

24
Answer: LCM of 6 and 8 is 24.

### What is the LCM of 8 and 5?

40
Answer: LCM of 5 and 8 is 40.

What is LCM and GCM?

The Greatest Common Factor (also known as GCF) is the largest number that divides evenly into each number in a given set of numbers. The Least Common Multiple (also known as LCM) is the smallest positive multiple that is common to two or more numbers.

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.

## What LCM means?

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 the HCF of 3 and 2?

1
Answer: HCF of 2 and 3 is 1.

How do you find the HCF?

HCF of two or more numbers is the highest common factor of the given numbers. It is found by multiplying the common prime factors of the given numbers. Whereas the least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.

How to calculate the LCM of 3 and 8?

Frequently Asked Questions on LCM of 3 and 8 1 Find the prime factorization of 3 3 = 3 2 Find the prime factorization of 8 8 = 2 x 2 x 2 3 Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the lcm: LCM = 24 = 2 x 2 x 4 Therefore, the least common multiple of 3 and 8 is 24.

## How to calculate the least common multiple of 3 and 8?

What is the Least Common Multiple of 3 and 8? Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor. The formula of LCM is LCM (a,b) = ( a × b) / GCF (a,b).

### How to find the lcm by listing multiples?
