What is the hcf for 15 and 25?
'5' The HCF (High Common Factor) can be found by dividing each number by its prime factors. Hence 15 = 3, 5. 25 = 5,5 '5' is common to both '15' & '25' , so it is the hcf.
What is the HCF of 15 and 40?
The GCF is 5.
What is the HCF of 45 and 40?
The Highest Common Factor (HCF) of 45 and 40 is 5. To find the HCF, you need to determine the largest number that divides both 45 and 40 without leaving a remainder. The factors of 45 are 1, 3, 5, 9, 15, and 45, while the factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The largest number that appears in both lists is 5, making it the HCF of 45 and 40.
Is 5 a common factor of 25 and 50?
Yes and the HCF is 25
What is the hcf of 160 and 200?
The highest common factor (HCF) of 160 and 200 is the largest positive integer that divides both 160 and 200 without leaving a remainder. To find the HCF, you can use the prime factorization method. The prime factorization of 160 is 2^5 * 5, and the prime factorization of 200 is 2^3 * 5^2. To find the HCF, you take the common factors with the lowest exponent, which in this case is 2^3 * 5 = 40. Therefore, the HCF of 160 and 200 is 40.
