### What’s the lowest common multiple of 24 and 30?

The LCM of 24 and 30 is 120. To find the least common multiple (LCM) of 24 and 30, we need to find the multiples of 24 and 30 (multiples of 24 = 24, 48, 72, 96 . . . .

**What is the GCF of 24 and 18?**

6

The greatest common factor is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

**What is the LCM of 7 18 and 21?**

Least Common Multiple of 7, 18, 21 Least common multiple (LCM) of 7, 18, 21 is 126.

#### What is the LCM of 24 15 and 36?

360

Answer: LCM of 24, 15, and 36 is 360.

**What is the LCM of 15 and 18?**

90

Multiply the factors to get the LCM. The LCM of 15 and 18 is 90.

**What is the HCF of 30 and 42?**

Answer: HCF of 30 and 42 is 6. Explanation: The HCF of two non-zero integers, x(30) and y(42), is the highest positive integer m(6) that divides both x(30) and y(42) without any remainder.

## What is the LCM of 20 and 30?

60

What is the LCM of 20 and 30? Answer: LCM of 20 and 30 is 60.

**What is the GCF of 24 30 and 18?**

As you can see when you list out the factors of each number, 6 is the greatest number that 18, 24, and 30 divides into.

**What is the HCF of 30?**

Factors of 30 (Thirty) = 1, 2, 3, 5, 6, 10, 15 and 30. Factors of 24 (Twenty four) = 1, 2, 3, 4, 6, 8, 12 and 24. Therefore, common factor of 30 (Thirty) and 24 (Twenty four = 1, 2, 3, and 6. Highest common factor (H.C.F) of 30 (Thirty) and 24 (Twenty four = 6.

### What are all of the common factors of 18 and 30?

The first step to find the gcf of 18 and 30 is to list the factors of each number. The factors of 18 are 1, 2, 3, 6, 9 and 18. The factors of 30 are 1, 2, 3, 5, 6, 10, 15 and 30. So, the Greatest Common Factor for these numbers is 6 because it divides all them without a remainder. Read more about Common Factors below.

**What’s the greatest common factor for 18, 30,?**

Greatest Common Factor. We found the factors and prime factorization of 18 and 30. The biggest common factor number is the GCF number. So the greatest common factor 18 and 30 is 6.

LCM(18, 20 and 30) = 180 The least common multiple 180 is a product of common & odd prime

#### What is the LCM of GCF?

The difference between GCF and LCM is self explanatory. While GCF is the largest number shared between the factors of two or more numbers, LCM is the smallest number that is divisible by both (or more) the numbers. To find either the LCM or the GCF of 2 or more numbers, it is necessary to factorize them.
