Quick Answer: What Is The HCF Of 16?

What is the LCM of 3 and 4?

The Least Common Multiple (LCM) of some numbers is the smallest number that the numbers are factors of.

Like the LCM of 3 and 4 is 12, because 12 is the smallest number that 3 and 4 are both factors for..

What is the HCF of 18 and 24?

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 GCF of 15 and 25?

5The Greatest Common Factor of 15and25 is 5. (the number itself and 1 do not count). The factor(s) of 25 is 5 .

What is 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.

Why do we calculate HCF?

In case of HCF, if some remainders are given, then firstly those remainders are subtracted from the numbers given and then their HCF is calculated. … Sometimes in case of HCF questions, the required remainder is given and when the remainder is not given, in those cases you will generally have three numbers given.

What is the HCF of 16 and 24?

8Example 21 Consider the highest common factor of 16 and 24 again. The common factors are 1, 2, 4 and 8. So, the highest common factor is 8.

What is the HCF of 16 and 18?

Greatest common factor (GCF) of 18 and 16 is 2.

What is the HCF of 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 is the HCF of 15?

Factors of 15 (Fifteen) = 1, 3, 5 and 15. Factors of 35 (Thirty five) = 1, 5, 7 and 35. Therefore, common factor of 15 (Fifteen) and 35 (Thirty five) = 1 and 5. Highest common factor (H.C.F) of 15 (Fifteen) and 35 (Thirty five) = 5.

What is the HCF of 5 and 25?

The hcf(25,35) is 5 .

What is the HCF of 12 and 36?

We found the factors and prime factorization of 12 and 36. The biggest common factor number is the GCF number. So the greatest common factor 12 and 36 is 12.

What is the HCF of 16 and 20?

4The highest common factor of 16 and 20 is 4.

How do you calculate 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.

What is the HCF of 32 and 16?

The common factors of 16 and 32 are 16, 8, 4, 2, 1, intersecting the two sets above. In the intersection factors of 16 ∩ factors of 32 the greatest element is 16. Therefore, the greatest common factor of 16 and 32 is 16.

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.

What is the HCF of 18 and 15?

The common factors of 15 and 18 are 3, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 18 the greatest element is 3. Therefore, the greatest common factor of 15 and 18 is 3.

What is the GCF of 12 and 18?

In terms of numbers, the greatest common factor (gcf) is the largest natural number that exactly divides two or more given natural numbers. Example 1: 6 is the greatest common factor of 12 and 18.

What is the LCM of 32 and 16?
