## What is the GCF of and 18?

Example: Find the GCF of 18 and 27 The factors of 18 are 1, 2, 3, 6, 9, 18.

The factors of 27 are 1, 3, 9, 27.

The common factors of 18 and 27 are 1, 3 and 9.

The greatest common factor of 18 and 27 is 9..

## How do u find the greatest common factor?

The greatest common factor, or GCF, is the greatest factor that divides two numbers. To find the GCF of two numbers: List the prime factors of each number. Multiply those factors both numbers have in common.

## What is the GCF of 2 and 4?

The prime factors and multiplicities 2 and 4 have in common are: 2. 2 is the gcf of 2 and 4. gcf(2,4) = 2.

## What is the GCF of 24?

Answer and Explanation: The GCF of 24 and 36 is 12. ‘GCF’ means ‘greatest common factor’. That’s the greatest, or largest, factor that the two numbers share.

## What is the HCF of 12 and 18?

Factors of 18 = 1, 2, 3, 6, 9 and 18. Therefore, common factor of 12 and 18 = 1, 2, 3 and 6. Highest common factor (H.C.F) of 12 and 18 = 6 [since 6 is the highest common factor].

## What’s the GCF of 3 and 18?

Greatest common factor (GCF) of 3 and 18 is 3. We will now calculate the prime factors of 3 and 18, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 3 and 18.

## What’s the GCF of 18 and 9?

Greatest common factor (GCF) of 9 and 18 is 9. We will now calculate the prime factors of 9 and 18, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 9 and 18.

## What is the GCF of 10 and 18?

Greatest common factor (GCF) of 10 and 18 is 2. We will now calculate the prime factors of 10 and 18, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 10 and 18.

## What is the formula of LCM?

The Least Common Multiple (LCM) of two integers a and b, usually denoted by LCM (a, b), is the smallest positive integer that is divisible by both a and b….Formula of L.C.M.Formulas To Calculate LCML.C.M formula for any two numbersL.C.M. = \frac{a\times b}{gcd\left(a,b\right)}1 more row

## What is the greatest common factor of 7 and 19?

Greatest common factor (GCF) of 7 and 19 is 1.

## What is the LCM of 18 and 7?

Least common multiple (LCM) of 7 and 18 is 126.

## What is the GCF of 24 and 18?

We found the factors and prime factorization of 18 and 24. The biggest common factor number is the GCF number. So the greatest common factor 18 and 24 is 6.

## What is the HCF of 15 and 21?

Greatest common factor (GCF) of 15 and 21 is 3. We will now calculate the prime factors of 15 and 21, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 21.

## What is the GCF of 33 and 15?

3Greatest common factor (GCF) of 15 and 33 is 3.

## What is the HCF of 9 and 18?

The common factors of 9 and 18 are 9, 3, 1, intersecting the two sets above. In the intersection factors of 9 ∩ factors of 18 the greatest element is 9. Therefore, the greatest common factor of 9 and 18 is 9.
