What is the HCF of 12?
Factors of 12 = 1, 2, 3, 4, 6 and 12. 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 12 and 16 HCF?
4
Thus, the HCF of 12 and 16 is ‘4’.
What is the HCF 2 and 12?
2
The HCF of 2 and 12 is 2. To calculate the HCF (Highest Common Factor) of 2 and 12, we need to factor each number (factors of 2 = 1, 2; factors of 12 = 1, 2, 3, 4, 6, 12) and choose the highest factor that exactly divides both 2 and 12, i.e., 2.
What is the HCF of 12 by prime factorization?
12 = 1 × 2 × 2 × 3. 56 = 1 × 2 × 2 × 2 × 7. Common factor of 12 and 56 = 1, 2, 2. Highest common factor of 12 and 56 = 2 × 2 = 4.
What are the prime factors of 12?
We know that 12 is a composite number, and hence it can be further factored into its prime factors. Thus, 12 can be written as the product of 2, 2 and 3, as both 2 and 3 are prime factors.
What are common factors of 12?
The factors of 12 are 1, 2, 3, 4, 6 and 12. The factors of 11 are 1 and 11. As 11 is a prime number, the common factor of 12 and 11 is 1.
What are the factor of 2 12?
For 2 and 12 those factors look like this: Factors for 2: 1 and 2. Factors for 12: 1, 2, 3, 4, 6, and 12.
What is the HCF of 15 and 12?
3
HCF Example The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.
What is the multiples of 12?
The multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144,… The multiples of 16 are 16, 32, 48, 64, 80, 96, 112, 128, 144, 160,… Hence the common multiples of 12 and 16 are 48, 96, 144,… and their LCM is 48.
What is the HCF of 12 and 14?
The HCF of 12 and 14 is 2. To calculate the Highest common factor (HCF) of 12 and 14, we need to factor each number (factors of 12 = 1, 2, 3, 4, 6, 12; factors of 14 = 1, 2, 7, 14) and choose the highest factor that exactly divides both 12 and 14, i.e., 2.
What are the factor of 12?
factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.
