## What is the HCF of 15 and 30?

The common factors of 15 and 30 are 1, 3, 5, and 15. The greatest common factor is 15. Example: What is the greatest common factor of 9 and 20?

## What is the highest common factor of 24 and 40?

The highest common factor (HCF) of two numbers (or expressions) is the largest number (or expression) which is a factor of both. Consider the highest common factor of 24 and 40. The common factors of 24 and 40 are 2, 4, and 8. So, the highest common factor is 8.

## How do you get 40?

To calculate the percentage, multiply this fraction by 100 and add a percent sign. 100 * numerator / denominator = percentage . In our example it’s 100 * 2/5 = 100 * 0.4 = 40 .

## What is the HCF of 5 10 and 15?

Factors of 15 = 1, 3, 5 and 15. Factors of 10 = 1, 2, 5 and 10. Therefore, common factor of 15 and 10 = 1 and 5. Highest common factor (H.C.F) of 15 and 10 = 5.

## What is the HCF of 16 and 24?

The greatest common factor of two (or more) numbers is the product of all the prime factors the numbers have in common. There are three 2’s common to both numbers, so 2*2*2 = 8 is the “greatest common factor” (GCF) of 16 and 24.

## What’s the prime factor of 40?

Answer and Explanation: The prime factorization of 40 is 2 × 2 × 2 × 5, or 23 × 5. To find the prime factorization of 40, we can use factor trees,…

## What is the HCF of 15 and 20?

5Greatest common factor (GCF) of 15 and 20 is 5. We will now calculate the prime factors of 15 and 20, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 20.

## What is the HCF of 45 and 75?

15The common factors of 45 and 75 are 15, 5, 3, 1, intersecting the two sets above. In the intersection factors of 45 ∩ factors of 75 the greatest element is 15. Therefore, the greatest common factor of 45 and 75 is 15.

## What is the HCF of 45 and 50?

Greatest common factor (GCF) of 45 and 50 is 5. We will now calculate the prime factors of 45 and 50, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 45 and 50.

## What is the HCF of 12 45 and 75?

12=2×2×3. 45=5×3×3. 75=5×5×3 .

## What is the HCF of 50?

Factors of 50 (Fifty) = 1, 2, 5, 10, 25 and 50. Factors of 70 (Seventy) = 1, 2, 5, 14, 7, 10, 35 and 70. Therefore, common factor of 50 (Fifty) and 70 (Seventy) = 1, 2, 5, 10. Highest common factor (H.C.F) of 50 (Fifty) and 70 (Seventy) = 10.

## What is the HCF of 15 and 35?

5Answer and Explanation: The greatest common factor of 35 and 15 is 5. The ‘greatest common factor’ is sometimes called the ‘GCF. ‘ The GCF of 15 and 35 is the greatest…

## What are multiples of 40?

Table of Factors and MultiplesFactorsMultiples1, 2, 4, 5, 8, 10, 20, 4040801, 4141821, 2, 3, 6, 7, 14, 21, 4242841, 43438641 more rows

## What is the prime factor of 45?

Students learn that the prime factorization of a number is the given number written as the product of its prime factors. For example, to find the prime factorization of 45, use a factor tree to find that 45 is 5 x 9, and 9 is 3 x 3. So the prime factorization of 45 is 5 x 3 x 3, or 5 x 3^2.

## What are the prime factors of 42?

The only way to write 42 as the product of primes (except to change the order of the factors) is 2 × 3 × 7. We call 2 × 3 × 7 the prime factorization of 42. It turns out that every counting number (natural number) has a unique prime factorization, different from any other counting number.

## How we can find HCF?

The highest common factor is found by multiplying all the factors which 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 which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.
