What is the HCF of 210 and 165?

The Highest Common Factor (HCF) of 210 and 165 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm, which involves dividing the larger number by the smaller number and then using the remainder as the new divisor until the remainder becomes zero. In this case, the HCF of 210 and 165 is 15.

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 480 and 1080?

The Highest Common Factor (HCF) of 480 and 1080 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, we need to factorize both numbers into their prime factors. The prime factors of 480 are 2^5 x 3 x 5, and the prime factors of 1080 are 2^3 x 3^3 x 5. To find the HCF, we take the common prime factors with the lowest exponent, which are 2^3 x 3 = 24. Therefore, the HCF of 480 and 1080 is 24.
