How do you work out the hcf of 210 and 385?
Prime factors of 210 are: 2, 3, 5 and 7 Prime factors of 385 are: 5,7 and 11 Common factors are: 5 and 7 and so 5*7 = 35 which is the hcf
What is the prime factorization of HCF?
Prime factorization is one of the ways you find the HCF.
Find the Highest common factor (HCF) of 18 and 24. Show working.?
The answer is as follows:The prime factorisation of the two number is:18 = 2*3*324 = 2*2*2*3The HCF is the product every number which appears in both lists (repeated appearances mean repeated inclusion in HCF):HCF = 2*3 = 6
When the hcf of two numbers is 1 it is called what?
The numbers are relatively prime or co-prime.
What is the hcf of 12 and 10?
The GCF is 2.
How many prime nos are there in 5 successive nos of avg 7?
2
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.
How can we Find HCF of 144 and 36 by prime factorization method?
Prime factors of 36 are: 2^2 and 3^2 Prime factors of 144 are: 2^4 and 3^2 Prime factors common to both number are 2^2 and 3^2 which when multiplied equals 36 making it the HCF
What is the HCF of 3 and 2?
Both 3 and 2 are prime. This means they cannot be broken down further into prime factors. As they are different, this means they will not have any common prime factors. Therefore the HCF of 3 and 2 is 1. The HCF of any two different prime numbers will always be 1.
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.
What ius the hcf of 66 prime?
At least 2 or more numbers are needed to find their hcf but 66 as a product of its prime factors is: 2*3*11 = 66
What are the prime factor of HCF?
Each HCF has its own set of prime factors.
How can you Express 121 as a sum of 2 prime nos?
11x11
What is the HCF of 2 co-prime numbers?
The GCF is 1.
What is the HCF of 120 and 180?
The Highest Common Factor (HCF) of 120 and 180 is the largest number that divides both 120 and 180 without leaving a remainder. To find the HCF, we need to factorize both numbers into their prime factors. The prime factorization of 120 is 2^3 * 3 * 5, and the prime factorization of 180 is 2^2 * 3^2 * 5. To find the HCF, we take the product of the common prime factors with the lowest exponent, which is 2^2 * 3 = 12. Therefore, the HCF of 120 and 180 is 12.
Which 2 nos have same LCM and HCF?
Any two of the same number. The GCF and LCM of 10 and 10 is 10.
How do you find HCF of product of 2 nos?
You find the HCF of the two numbers, not their product. Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the HCF
