The hcf of 45 and 40 is 5.
The Highest Common Factor (HCF) of 315 and 720 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 in the next iteration. Continuing this process, the HCF of 315 and 720 is 45.
