What is the HCF prime factor of 48 64 and 80?
The only prime factor these numbers share is 2. It is the only prime factor of 64, which is 2 to the 6th power. The hcf is 16, but that is not a prime.
Does the HCF of any two no is always a factor of their LCM?
If two numbers are expressed as ab and cb this is easier to work out. Assume that a and c have no common prime factors. Thus, the HCF of the two numbers will be b. The LCM is the two numbers multiplied by each other, divided by the HCF. So the LCM will be abc. b is a factor of abc, and so the HCF will always be a factor of their LCM.
What is the HCF of 99?
The Highest Common Factor (HCF) of 99 is 99. This is because 99 is a prime number, meaning it only has two factors: 1 and 99. Since there are no other common factors between 99 and any other number, the HCF remains 99.
What is the Hcf of 120 400?
The Highest Common Factor (HCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the HCF of 120 and 400, you can use the prime factorization method. The prime factorization of 120 is 2^3 * 3 * 5 and the prime factorization of 400 is 2^4 * 5^2. To find the HCF, you take the common prime factors with the lowest exponent, which in this case is 2^3 * 5 = 40. Therefore, the HCF of 120 and 400 is 40.
What are the HCF of 15 and 20?
To find the HCF, you first have to express both numbers as the product of their prime factors: 15 = 3x5 20 = 2x2x5 The next step is to identify any common prime factors. In this case both numbers have a 5 as a prime factor. Therefore the HCF of 15 and 20 is 5.
What is the HCF prime factor of 48 64 and 80?
The only prime factor these numbers share is 2. It is the only prime factor of 64, which is 2 to the 6th power. The hcf is 16, but that is not a prime.
When the numerator and denominator of a fraction are relatively prime?
When they have no factor in common, or their HCF is 1.
What is the HCF for 13 and 52?
To find the HCF of these two numbers, you must first split them into their prime factors: 13 = 13 52 = 2x2x13 The next step is to identify any common prime factors. In this case both numbers have 13 as a prime factor. Therefore the HCF of 13 and 52 is 13.
What is the HCF of 135 and 165?
Find the HCF of 135 and 165 prime factor method
What is the HCF prime of 90?
It is not possible to give a sensible answer to this question. The highest common factor (HCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
Are 39 and 182 relatively prime?
No. hcf(39, 182) = 13. Their highest common factor would be 1 if they were relatively prime.
What is HCF of 15 and 39?
To find the HCF of two numbers you first have to express them as a product of their prime factors. In this case: 15 = 3x5 39 = 3x13 The next step is to identify any common prime factors. In this case, both numbers have 3 as a prime factor. Therefore the HCF of 15 and 39 is 3.
Does the HCF of any two no is always a factor of their LCM?
If two numbers are expressed as ab and cb this is easier to work out. Assume that a and c have no common prime factors. Thus, the HCF of the two numbers will be b. The LCM is the two numbers multiplied by each other, divided by the HCF. So the LCM will be abc. b is a factor of abc, and so the HCF will always be a factor of their LCM.
What is the HCF of 99?
The Highest Common Factor (HCF) of 99 is 99. This is because 99 is a prime number, meaning it only has two factors: 1 and 99. Since there are no other common factors between 99 and any other number, the HCF remains 99.
How do you take out HCF of 3 and 15?
To find the HCF you first need to break the numbers down into their prime factors. In this case you'd get: 3 = 3 15 = 3x5 The next step is to identify any common prime factors. In this case, the only common prime factor is 3. Therefore the HCF of 3 and 15 is 3.
Can the HCF of two numbers be a factor of their LCM?
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
What is the HCF of 16 48 and 60?
The Highest Common Factor (HCF) of 16, 48, and 60 is 4. To find the HCF, you need to factorize each number into its prime factors. The prime factors of 16 are 2^4, the prime factors of 48 are 2^4 * 3, and the prime factors of 60 are 2^2 * 3 * 5. The HCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 = 4.
