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 630 and 294, you can use the Euclidean algorithm or prime factorization method. By prime factorizing 630 (2 x 3^2 x 5 x 7) and 294 (2 x 3 x 7 x 7), you can identify the common prime factors and determine the HCF, which in this case is 42.
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
Prime factorization is one of the ways you find the HCF.
The numbers are relatively prime or co-prime.
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
2
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.
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
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.
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.
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
Each HCF has its own set of prime factors.
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.
The GCF is 1.
11x11
Any two of the same number. The GCF and LCM of 10 and 10 is 10.
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
