What is the HCF of 210 and 165?

Answer 1

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.

Answer 2

The HCF of 165 and 210 is 15.

The LCM is 2310.

Answer 3

210 = 2 x 3 x 5 x 7

165 = 5 x 3 x 11

HCF = 2 x 3 x 5 x 7 x 11 = 2310
