The highest common factor is found by multiplying all the factors that appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3, which is 12. The lowest common multiple is found by multiplying all the factors that appear in both lists: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5, which is 360.

Just so what is LCM and GCF with example?

Greatest Common Factor (GCF)

A common multiple is a number that is a multiple of two or more numbers. Common multiples of 2 and 3 are 0, 6, 12, 18. The least common multiple (LCM) of two numbers is the smallest number (non-zero) that is a multiple of both numbers.

Also, what is the LCM of 70 90 and 140?

The LCM of 90 and 140 is 1260.

Also what is the LCM of 8 and 12?

That least common multiple (LCM) of 8 and 12 is 24.

What is the GCF calculator?

The greatest common divisor (GCF or GCD or HCF) of a set of integers is the largest positive integer that can be divided into all numbers without a remainder. For example, for the numbers 18, 30, and 42, the gcd = 6.

## What is the gcd of 12?

Find the greatest common divisor

Two numbers Divisor Greatest common divisor
9 and 12 9: 1,3,9 12: 1,2,3,4,6,12 3

## What is a composite number in math?

Compound number. more An integer that can be formed by multiplying other integers. Example: 6 can be formed by 2 × 3, so it is a composite number. But 7 can’t be formed by multiplying other integers (1×7 would work, but we said we should use other integers), so it’s not a composite number, it’s prime.

## What is the LCM of 4 and 8?

LCM of 4 and 8 is 8. To get LCM, multiply the common prime factors of the two given numbers by the remaining unusual factors. Therefore LCM of 4 and 8 is 8.

## What is a prime factor?

A factor that is prime. In other words, any of the prime numbers that can be multiplied to give the original number. Example: The prime factors of 15 are 3 and 5 (because 3×5=15 and 3 and 5 are prime).

## What are the factors of 24?

24 Do you think Do you have a snow problem? Try this:

• 24 is a composite number.
• Prime factorization: 24 = 2 x 2 x 2 x 3, which can be written as 24 = 2³ x 3.
• The exponents in prime factorization are 3 and 1.
• Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.
• Factor pairs: 24 = 1 x 24, 2 x 12, 3 x 8, or 4 x 6.

## What is the LCM of 9 and 12?

The LCM of 9 and 12 is thirty-six.

## What is LCF?

Please read our privacy policy. A common multiple is a number that is a multiple of two or more numbers. The common multiples of 3 and 4 are 0, 12, 24, . The least common multiple (LCM) of two numbers is the smallest number (non-zero) that is a multiple of both.

## What does GCF mean?

## What is LCM in mathematics?

Mathematical definition of terms. Least Common Multiple (LCM) The Least Common Multiple (LCM) of 2 numbers is the smallest number into which they are both evenly divisible. A good way to find the least common multiple of 2 numbers is to multiply both numbers by 1,2,3,4,5 and then find the first multiple that occurs in both lists.

## What is GCF used for? for?

A common use of the GCF is to simplify a fraction by dividing both the numerator and denominator by the GCF of both. Another way to find the LCM for two numbers is to divide the product of the two numbers by the GCF for the numbers. For example, the GCF of 36 and 60 is 12. The product of 36 x 60 = 2,160.

## What is the LCM of 6 and 9?

The LCM of 6 and 9 is 18.

## What is the GCF and LCM of 9 and 12?

Least common multiple of 9 and 12. The least common multiple (LCM) of 9 and 12 is 36.

## What is an LCM example?

Example: find the least common multiple of 4, 6 and 8. Multiples of 4 are: 4, 8 , 12, 16, 20, 24, 28, 32, 36, multiples of 6 are: 6, 12, 18, 24, 30, 36, multiples of 8 are: 8, 16, 24, 32, 40, . So the least common multiple (I can’t find a smaller one!) is 24

## What is the LCM of 12 and 15?

The least common multiple (LCM) of 12 and 15 is 60.

## What is the LCM of 8 and 10?

What is the LCM of 8 and 10? The lcm of 8 and 10 is 40.
